--- Comment #1 from Maxim Levitsky maximlevitsky@gmail.com 2011-06-20 15:04:12 --- This is very interesting beast.
First of all, I also notice similar problem with compiz, not that often though. Once again, open totem, maximize, minimize, boom. It doesn't happen often, but when I start watching videos often it bites. Also XV sometimes hangs the system without any user intervention.
Now that commit that Jan Seiffert bisected looks very very suspicions. I can say I almost sure he found something very interesting.
Kudos to Jan Seiffert

--- Comment #3 from Marcin Slusarz marcin.slusarz@gmail.com 2011-06-20 16:32:43 --- Hmm, few days ago on irc someone else reported similar bug and Ben provided this patch: http://members.iinet.net.au/~skeggsb/0001-drm-nouveau-fix-assumption-that-se... which seemed to fix it.
I'm not sure why he didn't apply it yet.

--- Comment #4 from Jan "RedBully" Seiffert kaffeemonster@googlemail.com 2011-06-20 19:45:13 --- The patch from comment #3 is in nouveau/linux-2.6, but on the second page ;) http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=b16a5a18ff994532120... It is taged as drm-nouveau-fixes, so it should go into Linus Tree.
Hopefully fast! I had a Linux-3.0.0-rc3 git tree here, applied the 3 patched till drm-nouveau-fixes by hand (left out the endian fix, no BE here), and yes, the problem is gone.
I repeat: This seems to resolve the problem!
Where can i put my "Tested-by: Jan Seiffert"?
Greetings Jan
