Description of problem:
I have seen two occasions of the kernel collapsing with a recusive fault,
with the versions listed below. See attachments for backtraces. On both
occasions, I had been playing around with video, desktop effects, etc. In the
first instance, X segfaulted and the kernel fault was reported. In the second
case, I had been playing videos without problems. A few hibernate/thaw and
suspend/resume cycles later, with desktop effects enabled, I saw something
similar.

This hardware has always behaved admirably in the past (i.e. F8 and F9).

I've filed this under kernel, but could it be some DRI/GEM funniness or X
somehow scribbling over someone else's memory? This is a notebook with an Intel
X3100 chipset.

Version-Release number of selected component (if applicable):
kernel-2.6.27.7-134.fc10.x86_64
kernel-2.6.27.9-163.fc10.x86_64
xorg-x11-drv-i810-2.5.0-4.fc10.x86_64

How reproducible:
Intermittently, but circumstances surrounding it seem correlated.

Steps to reproduce:
Play videos using Xv extension. Try desktop effects. Suspend/resume and
hibernate/thaw a few times.
