Bug Description

My X server crashed, and didn't manage to start back up properly. I had to reboot, and after doing so, found this in the log.

Hi Matt,

I brought this bug up in the kernel team meeting. Seems we have some i915 related patches coming down the pipe via some stable release updates. A kernel with these patches should come out after Jaunty Beta gets released. It would be great if you could retest at that point. I believe apw might throw a test kernel together in the meantime as well. Thanks.

I am happy to test; however, note that I cannot reliably reproduce this bug.

I think I have encountered the same/similar bug.
HP HDX18 Notebook running up-to-date jaunty amd64.

~$ uname -a
Linux thomas-hp-hdx18 2.6.28-14-generic #47-Ubuntu SMP Sat Jul 25 01:19:55 UTC 2009 x86_64 GNU/Linux

The X-server crashed (screen black) suddenly. (working with firefox and evolution)
(This is the heaviest bug I've ever seen on ubuntu since years.)

I'll attack additional files.

Please look at tank_syslog.log at line 2131:
Aug 1 23:05:30 thomas-hp-hdx18 kernel: [ 1265.601591] Dumping ftrace buffer:
(i think at that time was the crash)
