Bug Description
Apport log atttached: apport.
System seems to work fine if you switch to tty2-9. However if you log in through Unity,the system fails to bring up the desktop environment. Mouse movements, keyboard actions are unresponsive after logging in. I've tried also booting the 12.04 image from a usb key and using the "Try ubuntu" option and the issue is still valid.
I was able to grab the apport dump via crtl alt f2 terminal.
lsb-release info:
12.04 Precise, kernel version 3.2.0.23.
This issue is not a problem with 11.10 or 11.04.

After the issue occurs, I am unable to access tty9. The keyboard and system are both unresponsive at this point. Running unity --reset before issue occurs has no effect.

I was able t reproduce the situation and quickly switch to tty9 before the lock up occured. I am still unable to type anything in any tty, however I see the following errors printed to the screen:
BUG: soft lockup - CPU#0 stuck for 22s [apport-gpu-error 2777]
and
BUG: soft lockup - CPU#1 stuck for 22s [compiz-error:2290]
It will do this for every logical cpu.

Thanks Jeff. That appears to be a kernel message. If you're sure "BUG: soft lockup ..." is directly related to this bug then we should assign it to the Linux kernel, or the graphics driver.

@Jeff - Please provide the log files for this bug and test with the upstream kernel when you get a chance
Jeff Marcom (jeffmarcom) wrote : | #10 |
@Brad, I can't pull the apport logs with X, because it tries to open firefox. Is there a way around this?
Jeff Marcom (jeffmarcom) wrote : | #11 |
I tried updating to quantal rc3 3.5.0 kernel version. X now starts, system is completely unresponsive. I can't switch tty.

I tried running running apport through an SSH session so that I would have access to firefox for openid authentication.
I don't think I can grab the required logs due to the nature of this bug.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.
If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

We can perform a bisect to find the exact commit that caused this regression. Can you test the following kernels and report back if either exhibit this bug:
v3.0 latest: http://
v3.1: http://
v3.2-rc1: http://

This particular system was certified with 3.0. Kernel 3.1 worked without issue. The 3.2 rc1 presented the bug.

Sorry Joseph, I think grub was loading the base 3.2.0.23 when I thought I was testing rc1.
In any event I went through the following path and found the first instance I saw where the bug was introduced:

Jeff, could you please try logging into tty2-9 and running:
unity --reset
Warning: That will reset any options you've configured in CCSM back to defaults. But for some people, it does solve this problem.
