Hi, today, exactly this error occurred to me after applying an 'apt-get
dist-upgrade' to a system.

Here some system details:
CPU:  Intel Core i5-2500 CPU @ 3.30Ghz
OS:   Ubuntu 12.04.02  (64bit)
NEW KERNEL:   3.0.2-39-generic (buildd at lamiak)   #62-Ubuntu SMP Thu Feb 28
00:28:52 UTC 2013 (Ubuntu 3.2.0-39.62-generic 3.2.39)

OLD KERNEL:   3.0.2-38-generic (buildd at akateko)  #61-Ubuntu SMP Tue Feb 19
12:18:21 UTC 2013

CONFIGURATION:
The OS-configuration is almost as distributed. No heavy tunings.

NOTE:   The 2D-version of the Unity desktop is used. At an earlier dist-upgrade
 (might be 2.0.3-35) the the 3D-Unity panel got difficulties in a way that the
graphics adapter did not return the rendered objects like the buttons etc.
Rebooting the system did not solve the problem when it occurred. Only after
making a real power off of the system restored the functionality. I assumed,
the reset of the graphics adapter did not succeed.


I know, the kernel is the distribution specific one and not in active
development any more. But the chance to advance the filed problem is, that on
this system the error does occur almost immediately after login when using
3.0.2-39. Using the previous kernel 3.0.2-38, everything seems to be stable as
before the upgrade.

I have access to the system for the next two weeks, so if you would like to get
some details and testing, I'm willing to do my best (being almost typical user
with some unnoticeable administration experience).

So tell me what information you would like to get and how I should gather it.
