Comment 5 Chris Wilson 2011-03-31 12:51:41 UTC 
Indicative of memory corruption.

Bryce, what's the breakdown on the 2.6.38-7 kernel? Is there a convenient way to know if contains the 2011Q1 patches?

Zhenyu has some patches for some S4 issues at http://people.freedesktop.org/~zhen/snb_desk_suspend_0323/ but cf bug 35648 we know we have some unresolved issues.

2.6.38-7 is upstream 2.6.38 when it comes to drm. He did try http://kernel.ubuntu.com/~sarvatt/2011Q1/ to be sure the problem existed there too. It only seems to be happening on that one machine (Inspiron 15R), I haven't been able to reproduce this on an E6420 or a sandybridge vostro.

I'd say it is a duplicate of bug #35648.
