I use notebook with M82==RV620. When playing with KMS I get lock up after 5-20 secs of using KDE4. Sometimes it's just black screen, sometimes it's black, sometimes SysRq work, sometimes not. Does following commit look like guilty one? AFAICS it should touch disabled acceleration only, right? And xf86-video-ati enables EXA for me: (II) EXA(0): Driver allocated offscreen pixmaps (II) EXA(0): Driver registered support for the following operations: (II) Solid (II) Copy (II) Composite (RENDER acceleration) (II) UploadToScreen (II) DownloadFromScreen (II) RADEON(0): Acceleration enabled http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=75c8129893d78fd0cbe5c26580cadd6001d904fc 75c8129893d78fd0cbe5c26580cadd6001d904fc is the first bad commit commit 75c8129893d78fd0cbe5c26580cadd6001d904fc Author: Jerome Glisse <jglisse@redhat.com> Date: Thu Oct 1 18:02:14 2009 +0200 drm/radeon/kms: Fix R600/RV770 disable acceleration path When acceleration doesn't work we should free associated memory and stop GPU block responsible for hardware acceleration so we don't waste resource or let think one component of the driver that a GPU feature is working/running while it doesn't actualy work.

Did you update any other parts of the stack like mesa or xf86-video-ati? Might be related to bug 24425 if kwin uses GL.

We discussed this shortly on IRC, didn't yet have time to update bug report. I've updated openSUSE 11.2 from milestone 6 to 8. This means update of: 1) KDE 4.3.0 → KDE 4.3.1 2) X Server 1.6.3 → X Server 1.6.4-RC1 (and of course a lot of other packages, but hopefully not significant). I don't use Mesa r600 driver, so this should not be 3D/GL related. I've just reinstalled old milestone 6 and I can confirm it works again. I plan to upgrade single packages to find problematic one. First however, I'd like to hunt some KMS crasher in connectors list. I'll update bug report title as I find problematic package.
My bisecting was based just on luck. One sessions per ~20/30 works fine, that's all. Reported bug #24535.
