Yesterday I upgraded to kernel 2.6.35 and I had a lockup after playing for a few second at openarena. The day before I had played for a few minutes without any issue (testing r300g) so I immediately suspected the kernel.
I'm using a radeon x550 (rv370) with yesterday git snapshot of mesa and xf86-video-ati and xorg-server 1.8.2.
Both r300c/DRI/UMS and r300c/DRI2/KMS dont' seem to suffer from the issue, only gallium. Nothing unusual in the logs.
I bisected from 2.6.34 (good) to 2.6.35 (bad) and git bisect pointed to commit eb1f8e4f3be898df808e2dfc131099f5831d491d
eb1f8e4f3be898df808e2dfc131099f5831d491d is the first bad commit commit eb1f8e4f3be898df808e2dfc131099f5831d491d Author: Dave Airlie airlied@redhat.com Date: Fri May 7 06:42:51 2010 +0000
drm/fbdev: rework output polling to be back in the core. (v4)
After thinking it over a lot it made more sense for the core to deal with the output polling especially so it can notify X.
v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings.
v3: add config lock take inside polling, add intel/nouveau poll init/fini calls
v4: config lock was a bit agressive, only needed around connector list reading. otherwise it could re-enter.
glisse: discard drm_helper_hpd_irq_event

I had to skip a few revisions because opengl didn't work at all and one revision I'm not exactly sure it crashed for the same issue (the symptoms were slightly different, it crashed after maybe two minutes instead of 5-30s) so I'm not sure that that's the real culprit.
The bisection run took me a few hours and a lot of reboots, so I'm not exactly eager to try it again...
