The issue does not manifest on mainline kernel - 5.5.16-050516-generic

Experiencing the exact same problem on a Dell XPS 13 9630 since upgrade to kernel 5.3.0-46.

When problem is triggered, I can still move the mouse pointer for 2-3 seconds but can't interact with the desktop or any apps (clicking or typing does nothing). After that the mouse pointer stops for about a second. And then it all comes back; the clicks and keys that I types during the freeze comes flushing back...

Also noticed that when I'm on a telco, sound and video is completely unaffected throughout the freeze.

Tried upgrading to kernel 5.3.0-47 which is in the Ubuntu proposed repository. Still get the freezes, but now it seems that the mouse pointer doesn't stop--only the interface stops responding for 2-3seconds and then it all jumps back in action again.

Also there's a new line in the journal about an

This is probably the same as bug #1871867, can you confirm?

I've had this bug ever since upgrading to Ubuntu 18.10 (i.e. the Linux 5.3 kernel series). However before the 5.3.0-46-generic update (when I was on 5.3.0-45-generic and earlier versions), I had this issue (freezes of around ~10s) only a few times per day. After the 5.3.0-46-generic update, this bug happened several times per hour, sometimes repeating in the timeframe of minutes.
Though I only rarely get the "GPU HANG: ecode 9:0:0x00000000, hang on rcs0" message prior to the "Resetting rcs0 for hang on rcs0" message, for what's it worth.

To put this into numbers, from April 4 to April 9 (daily usage), I only got 6 freezes, whereas since the update to 5.3.0-46-generic (which I performed on April 10), I've got 122 hangs already. This makes using the whole system really annoying.

There are some interesting discussions about this bug on https://bbs.archlinux.org/viewtopic.php?id=250765, though note that there seem to be multiple bugs and it got worse with later kernel versions, including unrecoverable freezes on kernel 5.4 (which were reported in Ubuntu as bug #1861395).

I've reverted to Linux 4.19 LTS mainline kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/ for now, and haven't had any more freezes yet.

I agree, it seems exactly the same as bug #1872009

I have uploaded a test program (needs SDL1.2) that kind of immediately triggers the hang
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872009/+attachment/5352362/+files/test.exe

I'm sorry I realized you need more dependencies to run my test program, it's going to be complicated.

But I think any program that intensively sends data to the GPU should trigger the problem as well

OK here is a new version, I think now you just need to do

sudp apt install libsdl-ttf2.0-0
./test.exe

it should work

interestingly, my demo runs also 25% faster on 5.3.0-45 than on 5.3.0-46...

and 50% faster on 4.4.0 :(

Hello all, i think i have the same issue. Encountered on Ubuntu 18.04 and kernels 5.3.0, 5.4.31, 5.5.16 and 5.5.6 (ppa mainline build). I'm in a virtualized VM with Proxmox
I can EASILY reproduce it within a minute (start Kodi for example).

       Note: Lot of bugs linked to this not stable kernel BUT no more CPU HANG for the moment...
Hope it helps.

FWIW, I'm experiencing very similar symptoms on the same kernel (5.3.0-46-generic), but on different hardware: This is a Lenovo ThinkPad E490. One thing that makes it *much* more frequent is running jackd with realtime priority. Running with ardour and jack, during the freezes audio proceeds normally (even MIDI events and synths work fine), but keyboard, mouse and monitor freeze. This occurs about once a minute!
I've also experienced longer crashes (gave up and rebooted after a minute) when performing skype calls or just watching youtube, but those are far less frequent.

On my Dell XPS15, the frequency of the freezes depends on what I am running. While browsing, doing e-mail, terminal work and the like, it freezes maybe once every 10 minutes. But while playing Wesnoth, it freezes at least once per minute(!). It doesn't matter if I run on the i915 or the Nvidia gpu. The freezes are funny, because everything BUT the mouse freezes. I can move the mouse pointer around, but everything else is stuck for 5-8 seconds or so. I run i3-wm straight on X with no desktop environment on Ubuntu 19.10 with the 5.3.0-46-generic kernel.

...and no freezes before the update to the 5.3.0-46-generic kernel.

I can reproduce this bug by starting a call via zoom.us. The bug exists on 5.3.0-46-generic, previous kernel 5.3.0-45-generic works fine.

Update: I just tried the recently released linux-image-5.3.0-48-generic that was made available through eoan-proposed, but I still get the `Resetting rcs0 for hang on rcs0` error, so it's back to mainline 5.4.28-050428-generic for me.

Experiencing the same issues on linux mint 19.3.

Running to dual screen and also noticed that the size settings(icon size) on my second panel get reset to default... nut sure when it happens tough

I was also running into pretty horrendous graphics perf (with bionic), and fixed it after I did the following (did all at once so not sure which one did it):

- updated to the 5.3.0-51 kernel
- set the java2d option to opengl (from #82) - although I had issues in other apps too
- updated the Xorg server to xserver-xorg-hwe-18.04 (+ other hwe drivers)

My guess is that the last one is what did the trick. Much better for the last couple of days.

Another occurrence of this bug for me too, unfortunately:

[23965.091992] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0

This is the first for me in a week of using 5.3.0-52-generic so it's definitely less common.

Hello, it took me few seconds running Kodi to encounter the problem with 5.3.0-52.46 from https://kernel.ubuntu.com/~arighi/LP-1861395/5.3.0-52.46+lp1861395v1/

[ 181.891827] i915 0000:00:10.0: Resetting chip for hang on bcs0

In my case, the problem occurs more with 5.3.0-52 than 5.3.0-51.

To be clear 5.3.0-51 did NOT include the backported patches.
Proposed 5.3.0-52.46 had some and 5.3.0-52.46+lp1861395v1 had more.
Out of curiosity could the people who are still having hangs on the 5.3.0-52.46 proposed or 5.3.0-52.46+lp1861395v1 kernel have different generations of CPUs?

I've got a Coffee Lake CPU and the patches seemed to do a better job of fixing issues for me.
Perhaps we really have two different issues here.

@pcworld we saw similar behaviour. What is your CPU model?
Here is mine:
# grep "model name" /proc/cpuinfo
CPU model name : Intel(R) Core(TM) i3-8100 CPU @ 3.60GHz

@rhardy I have an i5-8250U and hangs have stopped ever since updating to the proposed 5.3.0-48-generic kernel (didn't try newer kernels yet).

As written in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/comments/118,

I had no hangs with "5.3.0-52-generic" or the extended one "lp1861395v1"

I did not check the logs with "5.3.0-52.46+lp1861395v1" but with the previous version the number of entries where very limited.

Unfortunatly I had to rollback to 5.3.0-51 as docker integration was a totally broken and preventing daily work.

In the meantime, I tried to upgrade to Ubuntu 20.04 with kernel 5.4.0x but the upgrade broke docker and even using docker.io instead of docker-ce did not fix the issue, as docker-ce is not yet available on 20.04.

I did not have the time to check for the "hangs" on 20.04 with kernel 5.4.0 but I can give a try if needed.

Later on, I'll probably do a format to perform a clean install on 20.04 to check is docker can work.

My laptop is a Dell Precision 7450 with an Intel i9-9880H.

Hmm so patches were effective for:
i5-8250U Kaby Lake R i.e. Gen 8
i9-9880H and i3-8100 both Coffee Lake Gen 9

It's hard enough debugging this directly on hardware. Doing it in a VM isn't going to be helpful.
Which CPU models are still failing with 5.3.0-52.46 or 5.3.0-52.46+lp1861395v1?

i7-1065G7 Ice Lake Gen 10 is still showing issues with 5.3.0-52

Strange, i have an i7-1065G7 and haven't had the issue since upgrading to 5.3.0-52. @benjamin-gemmill, what are you doing to test the issue. Maybe i can replicate on my system to see if i get the error to. So far i've been error free since April 30th on this kernel.

For me initially I saw it when working with large office documents and when attempting to do certain 1080p A/V playback. When it really got bad I couldn't use a browser as it was happening all the time.

I had the issue with Mint cinnamon desktop running kernel 5.3.0-46-generic.

Reverted back to 5.3.0-45-generic and it was resolved.

I noticed it mostly when using Webstorm IDE, although I don't think it was specific to this application. Intermittent but very frequent.

i7-9700k is failing..

I had a problem for a while, with PHPStorm being laggy on ubuntu (had this problem for over a year)
Recently lag became unusable, after I tweaked a few things in ubuntu config (i think I increased swappiness)
In Intellij discussion they linked to this linux kernel ticket.

Lags in a way of:
Phpstorm window freezes for 5 seconds
sometimes phpstorm does not unfreeze, need to kill the process
laggy scrolling inside Phpstorm file window
sometimes freezes inside settings menus
laptop fan spins up audibly more than usual
google chrome can become laggy while running phpstorm

Could not figure out how to upgrade kernel version, because I already had stable one

Upgrade to 19.10 did not help, kernel stayed the same version

After I did upgrade to 20.04, it seems so far that problems disappeared. Now kernel is 5.4.0-29-generic

I can also confirm that after upgrade to Ubuntu 20.04 with kernel 5.4.0-28-generic (12 days ago) there was not a single occurrence of this GPU HANG - on both machines I reported earlier.

Upgrade to 5.3.0-52-generic (5.3.0-52.46) last week has fixed the problem completely.
No more reset messages in dmesg with daily use

I've been running a couple of days not on the new release from eoan-proposed: 5.3.0-53-generic and this solved the docker issues introduced by earlier versions. So far no GPU hangs either. Not sure if anything related to this bug was changed in -53 in comparison to -52, but it's looking good.

My CPU is an Intel i5-7200 (with Intel HD 620)(Kaby lake). I can reproduce the issue running Kodi with 5.3.0-52.46+lp1861395v1

running 5.3.0-52-generic for a couple of weeks I still have occasional hangs, maybe not triggered by the same things. It seems for instance to happen when I open a PDF from within chromium-browser.
It lasts 3-4 seconds.

Since Linux X 5.3.0-53-generic it seems that I don't experience the hangs any more, but idle power consumption severely degraded: 5.3.0-51 uses 2/3 of the power that ..-53 uses. It's also worse than on 4.15.

5.3.0-53-generic solved the problem for me (xubuntu 19.10). No problems or rcs0 messages for 2 days now.
Thank you for your help.

Solved in 5.3.0-53-generic for me.
In may case GPU is not always at 100%. It is scaling frequency well from 350Mhz to max

I looked at this again. The GPU does scale down sometimes. But still the power consumption has without any doubt degraded a lot between 51 and 53 minor versions. The difference is immediately seen by either by looking at powertop or the power consumption or expected battery time in freshly booted kernels respectively. 53 only last 2/3 of the time that 51 lasts.

I've tried Ubuntu 20.04 (5.4.0-33-generic) hoping it will be better. But it's not the case; i've encoutered the problem quickly, even without using Kodi for stressing the GPU. Here the problem froze completly the system; hard reboot is the only way out. Will come back to Ubuntu 18.04 and 5.3.0-53 generic.
For info, here is the syslog with the problem:

Hello, it seems that there is no more activity on this bug. But i still face i915 CPU hangs and resetting. How can i have it solved ? Should i create another bug ? Thanks for your help.

It was solved, yet I am now on kernel 5.4.0-43 and I am hitting this now again since a week when using Jetbrains products. Clearly a regression, how could this 've happened. The linux-image* package changelog is pretty much worthless to investigate this.

You still can't edit comments on LP :S?

I am running kernel 5.4.0-42 instead of the earlier mentioned 5.4.0-43

Confirming, only Blender is affected in my case. Kernel 5.4.0-42, Intel UHD Graphics 620 (rev 07).

Same story here on Ubuntu 20.10.
Kernel version 5.8.0-25-generic on Dell XPS 15 9570, with Intel UHD Graphics 630 (Mobile).

I am seeing a very similar issue on my Lenovo T480s while using the Intel UHD Graphics 620 (rev 7).
A simple example is that YouTube videos in any browser (Chrome/Chromium/Firefox/etc.) while in the browser window play at 60fps but as soon as you use full screen it falls back to 30fps on the latest 5.4 kernels (-54,-53,-52). I did a quick test and booted a 4.15.0-123 kernel and that seemed to resolve the problem. Seems like a regression.

This doesn't seem to be fixed with recent Ubuntu kernels.

I have constant GPU hangs too.
