Bug Description

[IMPACT]

renders IVB GT1 systems basically inoperable, with massive distortion on screen

also affects systems on the certification queue

[TESTCASE]

boot 12.04 on a IVB GT1 (HD2500) system

[Regression Potential]

None, the changes are oneliners to reduce the max thread count on IVB GT1, which matches the current (internal?) intel specs

[NOTE]

The mesa update is added on top of a current SRU in -proposed, which is already being tested elsewhere. This commit should not risk that SRU, or vise versa (mesa got an exception from the TB)

--

I have a Intel 3570 CPU (Ivy Bridge) with built in 2500 graphics [1].
There is a lot of artifacts on screen, both in lightdm and in unity. There more or less impossibly to read any text on screen.
I have tested quantal and the packages from ppa:xorg-edgers/ppa without any improvement. I had high hopes what xf86-video-intel 2.20.2 was the solution because it contains ivy bridge fixes, but still no result. [2]

Note (link 2):
"For the last 9 months, since 2.16.901, we have been shipping a driver that
does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling
the GPU to use an invalid number of threads for the pixel shader and this
in turned caused the GPU to hang."

With a plain install of precise I only see artifacts, but X hangs (hard) when I'm using quantal or the packages from ppa:xorg-edgers/ppa

My current ugly workaround is to remove the intel driver and let X fall back to something else, not a perfect solution but the system is usable.

[2] http://lists.freedesktop.org/archives/xorg/2012-July/054947.html

Currently the system is running 12.04 with ppa ppa:xorg-edgers/ppa.
I have xserver-xorg-video-intel 2:2.20.2+git20120731.fd3a1236-0ubuntu0sarvatt~precise installed, the system hangs hard after I log in, or sometimes the GPU hangs and the screen goes to power save.

The system is not in use and I'm free to install and test whatever version and/or packages you want me to install.

Ubuntu 12.04 login screen

I'm getting Severe graphics corruption on my system. Graphics are fine in Windows 7. I have had the motherboard and CPU replaced, the issue still exists. Memory tests fine.

Symptoms:

1) The screen is covered in small wrong-color squares, almost like a corrupt JPG. Some screen elements render fine (e.g: the twm menu) while others are unreadable. Screen elements are not always drawn over when they go away. See the pictures attached for examples:

2) Driver hangs on any 3d type activity. glxgears, for example, will cause the screen to basicly freeze. The driver will then reset (as shown in dmesg). xorg-edgers drivers do not appear to freeze, but glxgears exits with "intel_do_flush_locked failed: Input/output error". glxgears registers 0.163fps or lower.

3) The image seems to display properly using the VESA driver. (Boot gentoo live-dvd with -nofb option)

4) With ubuntu and the xorg-edgers PPA, the corruption is present using both the "uxa" and "sna" AccelMethod options in xorg.conf

5) Sometimes, switching to a VT and back will clean up the image for a moment (i.e. until something moves) Also, after glxgears crashed with the error above, most applications were readable. However, redraw problems were still rampant, and trying to run glxgears again gives the do_flush_locked error above

I have confirmed these issues are present when booting the following distros:

Linux Mint 13 (64bit) Live-dvd
Ubuntu 12.04 (64bit) Install CD and Standard install
Gentoo 64bit Live-DVD 12.1 (regular boot, -nofb boots into vesa mode)

Turns out that the GPU is hanging with the latest xorg-edgers packages, same as before (see the dmesg output). However, the monitor is not resetting like it was (as if the resolution had changed) which is why I had thought otherwise.

We have obviously angered the hw gods here.

Can you try sacrificing some rc6 to see if that appeases them? Please append i915.i915_enable_rc6=0 to your grub boot parameters and see if that makes a difference.

Do you have any overclocking settings in your BIOS?

Revision history for this message
In , Jonathan (jdccdevel) wrote :

There are some, but none of them seem to make any difference as far as I can tell.

The Bios has a "Normal" setting in basic mode, which is supposed to disable all the overclocking features. It was the first thing I tried when I got the new motherboard and noticed the problem. In advanced mode, it gives you a LOT more overclocking options, but I'm not into overclocking, so I haven't used many.

Right now, almost everything is set to factory default except the RAM. It's set to 1600MHz, which is what the RAM is rated for. Previously, it was 1333MHz, and the problem still existed.

I have not tried fiddling with any of the more advanced settings. Right now, mostly they're all set to auto.

If there is any particular change you would like me to make, please let me know.

Thanks!

Logs from running driver snapshot 4a7334eb... from git

These are the log files generated by running the driver version found here:

Results: This _appears_ to fix the "corrupted jpg" look of the graphics on the initial login screen, and when running TWM.

However, when launching Unity (logging in), the computer crashes HARD. Previously, I could switch to a VT, and kill X. Now, I cannot. (I needed to ssh into the system to get these logs)

Also, glxgears crashes without showing anything.

    Reduce maximum thread count for IVB GT1 to avoid spontaneous combustion

    Somewhere along the way it seems that IVB GT1 was reduced to only allow
    a maximum of 48 threads, as revealed in the lastest bspecs.
