Bug Description

Binary package hint: linux-source-2.6.24

Don't know if this bug should be placed under the linux-source
I am quite pleased with hardy so far. The 2.6.24 kernel is working great without the need to specify noapic or alike.

The only problem I seem to have now, after upgrading to Hardy is that:

1. My laptop fails to turn off after shutdown
2. Suspend doesn't work
3. Hibernate doesn't work
4. Restart works fine.

I got a feeling that they are all very much related. Getting into a bit more detail:

1. My laptop fails to turn off after shutdown. The screen remains with a Red coloured Text line telling me that the computer is going to shut down but it never actually does it. (I can't remeber exactly what it says, I'll edit afterwards

2. Suspend doesn't work. The screen goes blank but the laptop doesnt' go into a low-power mode. I can still see cursor flashing and I can quickly change back to X by pressing Alt+Ctrl+F7, as I can change into other ttys

Actually it does go into a correct suspend mode (S3) if I input the following commands in console indicated at-->https://wiki.ubuntu.com/DebuggingKernelSuspend

     sudo su (to become root@machine, otherwise the following lines won't work)
     sync; echo 1 > /sys/power/pm_trace; /etc/acpi/sleep.sh force

After this my computer properly starts suspending, but when I try to resume I only get broken graphics all over the screen.

Following the indications on the page I searched for a 'hash matches' and found this:

[ 21.216267] Magic number: 8:715:321
[ 21.216353] hash matches device ttyya
[ 21.216497] hash matches device tty46
[ 21.216576] hash matches device 0000:00:02.0

I have no idea how to go on about 'removing the module prior to initiating suspend' ... to be honest I can't even tell what device 0000:00:02.0 is (my guess is that it is related with 00:02.0 PCI bridge: nVidia Corporation C51 PCI Express Bridge (rev a1))

So I'm quite stuck.

In short. The default power mangament in Ubuntu Hardy doesn't work for me as it did using 2.6.22. In that older kernel I had to use the noapic boot flag. This doesn't make any difference using 2.6.24. It still wont turn off, sleep nor hibernate properly.

Any suggestions of what I can do?

Thanks in advance..

My computer specs are: HP dv9343eu AMD Turion X2 TL-56, NVIDIA GeForce 7600 Go, 2x120 GB HD, Lastest F3.D BIOS updated. Broadcomm 4312 (which is finally working thanks to b43)

PS:Follwing the aforementioned indications I attach a bunch of output files

Hi Alej,

Thank you for the bug report. It is actually helpful to the development teams if bug reports target one specific issue against a specific set of hardware. I know you mentioned that the issues you see might be related, but it is best to have a separate report for each. We can easily mark them as duplicates later on. There are actually a few Nvidia suspend/resume issues already reported. What graphics driver are you using? Possibly take a look at bug 121653. Thanks!

I am having a similar problem.

Shutdown/restart do not work. They run through the shutdown process and get to "Will now HALT" or "Will now restart", and then just sit there.

Allright, I've been trying out different things, made a clean install of hardy alpha 5, and have found out the following....

If I boot with the following flag: noapic noirqdebug the system will shut down and/or restart properly. (noapic by itself works too) Wireless won't work, but that is a different story... After shutting down or restarting, next boot will boot properly, but it won't shutdown or restart properly (this being because I had not added any boot flags this time around)

If I boot without the noapic flag, whenever I try to shut down the computer won't restart nor shutdown. I have to manually press the power button to turn off and start again. This following time the laptop won't boot up properly (it'll stay stuck at "Loading Hardware drivers". I am therefore forced to turn off by pressing the power off button and add once again the noapic noirqdebug flag.

To put it shortly, I have a feeling that the new kernel fixes in 2.6.24 which have allowed me to boot without the noapic command are close to perfect but not there yet... the noapic flag is still necesarry intermittently....

I'll try to report more as asked or as I find out...

Thanks Alej,

Care to also attach your dmesg output, just curious if anything interesting is showing up. Also care to update the title and bug description of this bug report since it is now just focusing on the shutdown/reboot issues. You can click on the "Edit description/tags" link on the left hand side of this bug report. Thanks!

I'm having the some problem here. Using the new generic kernel for Hardy, my desktop will not shut down or reboot properly. (My laptop has no such problems). Instead, it hangs up at the shut down screen. I have to press the power button on the machine to reboot it. I never had to use the noapic commands before. Let me know if any other info will help.

My laptop now powers off, suspends and hibernates nearly to perfection (some strange screen flickering here and there) ..

I believe that the bug fixed at https://bugs.launchpad.net/bugs/200057 by Tim Gardner, the infamous Add DMI IO_DELAY support which has bugged so many HP Pavillion users solved this bug after its implemention in package linux - 2.6.24-14.24

Thankyou everybody for this. This bug should be closed
