Xorg crashed with SIGSEGV in MakeAtom() [Needs mesa 8.0.1]

[Logan Rosen]

A gray window appeared on my screen that I couldn't close, and then Ubuntu crashed and forced me out of my session.

lamalex also reported a bug with this backtrace:

http://paste.ubuntu.com/852021/

thumper thinks it may have been triggered by a recent compiz change to add an atom for focused, but that needs further sleuthing.

[Logan Rosen (logan)]

If this helps, this Xorg crash seems to keep happening in tandem with the compiz crash in Bug #926379 for me, which is a SIGSEV in intel_miptree_release(). I just experienced both crashes again five minutes ago while performing updates through Update Manager (forced me out of my Ubuntu session).

[Bryce Harrington (bryce)]

Aha, yes the intel_ crashes we believe are HiZ bugs, and should be fixed with mesa 8.0.1.

Test this PPA to be certain:

[Bryce Harrington (bryce)]

8.0.1 is now in the archive, so this bug *should* be fixed now.

mesa (8.0.1-0ubuntu1) precise; urgency=low

  * Merge from Debian experimental.
