Please try a 3.0 kernel. If that doesn't help, try this patch as well: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=4639dd21e759e32125adc7171abf6cb8140d54cf Created attachment 49628 [details]
kern.log with 3.0 kernel
Same behavior with the 3.0 kernel. Will try 3.0 plus patch next. Attachment shows messages. The last series of messages repeated indefinitely with display hung...
Does upgrading the ddx (xf86-video-ati) as well help? A custom 3.0 kernel with the small patch does not change the problem. Will try building the ddx from git. I built xf86-video-ati from the git sources. This introduced a new problem in X windows where the pixels are offset so that the display looks like very out of focus (fonts are not readable). Basically just built the driver with a --prefix option. It seems it may take a bit more effort to induce the problem with the 3.0 kernel, but it is a bit inconsistent, so presumably there is an asynchronous aspect to this problem. Happy to try more, but I need a bit of guidance. You might try an updated mesa as well. r600g being the relevant 3D driver for your card. Built mesa from git. Required several other updates as well. Ubuntu would not start unity (just reverted to login screen). Ubuntu classic (no effects) did start. glxgears ran at 2500 frame rate, whereas before it ran at vertical sync. But at least the screen was painted correctly with the new mesa. But eventually screen froze as before. Not sure I can do anymore -- just not experienced enough with this system stuff to have any confidence that I characterize the problem any better ;( For confirmation sake, this is the identical issue I am having (exact same system - mobo, gpu, etc) Just wanted to add another +1, here with a radeon hd 6870. The symptoms and the logs are very similar, including the video signal going away and then coming back. I've experienced the problem with the latest stable mesa/xf86-video-ati/xorg-server verions and on both kernels 3.0 and 3.1-rc4. I'm available to try patches, git snapshots etc. as needed. A very similar problem I've been having on HD6850 since last spring seems to have been fixed somewhere around kernel 3.0.7, mesa 7.11, video-ati 6.14.2 and xorg-server 1.11.1.901. Previously running Blender would always cause a lockup in under half a minute but for a couple of days I haven't been able to induce a lockup in any way. Closing reopen if it's still an issue with kernel 3.2 or newer and with mesa 8.0 or newer |
