[Bug 359931] Re: Jaunty intermittently hangs on Lenovo X61s related to graphics activity

[Ian Howson]

OK, I've had three crashes in the last hour. The actions I was doing during these were:
- 2x browsing through lightboxed images in Firefox
- closing a tab in Firefox

Usually, the mouse pointer hangs too. During one of these crashes, it
stayed alive.

I can log in through SSH. The Xorg process is in uninterruptible sleep.

If I kill -9 the Xorg process, the screen image changes to the attached
photo. The process doesn't actually go away (presumably due to the
uninterruptible sleep).

One of the crashes caused a kernel oops. The log is attached. Looking
through this, a kernel bug seems more plausible; I'll continue to gather
evidence and reassign if necessary.

The Xorg log shows no error messages after crashing.


** Attachment added: "dmesg output after kernel oops"
