--- Comment #3 from Knut Tidemann knut.tidemann@gmail.com --- I'm using mesa from git. (Right now: g4dbca86). I'm not able to bisect right now (I'm at work), but I'll give it a shot next week.
I'm suspecting VDPAU/UVD, because I tried to used it with adobe flash due to a red and blue color swap and I got this error after a while:
[drm:radeon_uvd_free_handles] *ERROR* Error destroying UVD (-22)!
And vdpauinfo stopped showing h264 and all the others, I was just left with MPEG2-variants (possibly the shader decoder?). After a reboot I was able to see all the supported codecs again.
I've now disabled the hw-decoding in flash to see if the crashes go away.
