[Bug 28326] still present in eisty

[Martin Rehn]

This bug is still present in Feisty as per today (xserver-xorg-
video-i810 2:1.7.4-0ubuntu1, linux-image-2.6.20-13-lowlatency
2.6.20-13.21).

I can go through several suspend/resume cycles with no problem
sometimes, but then as soon as an application tries to paint video to
the screen there is a crash. The crash does not occur until the video is
actually painted to the screen; the video window can be sitting behind
other windows on the desktop without causing a crash.

Description of a crash with feisty: when I bring the video window
forward it is all blue rather than containing any video. Then the screen
goes blank and starts to display a moving band of video artifacts
towards the bottom of the screen. I can still move the cursor mouse, but
the machine does not respond to e.g. ctrl-alt-f1, ctrl-alt-backspace,
ctrl-alt-delete. There is disk activity. The machine does shut itself
down gracefully when I press the power button.

I get the following in syslog, the last two messages repeating,
indicating, I presume, that kdm repeatedly tries to restart the X server
without success:

Apr  1 09:04:21 machine kdm[5191]: X server for display :0 terminated unexpectedly
Apr  1 09:04:22 machine gconfd (user-6570): Exiting
Apr  1 09:04:31 machine kdm_greet[27446]: Can't open default user face
Apr  1 09:04:37 machine kdm_greet[27446]: Internal error: memory corruption detected
