I would suggest trying newer versions of the userspace gfx stack (mesa, xf86-video-ati). GPU resets are usually caused by bad command combinations sent by the userspace drivers.
Status with following kernel and userspace stack versions: Kernel: 3.8.0 Mesa: 9.1.7 xf86-video-ati: compiled for 1.13.3, module version = 7.1.0
The system is more stable again. We had only one kernel freeze and this was preceeded by a failed GPU reset.
One root cause of the previously increased instability seems to be that the second X server runs wine-1.4. Wine requires also the 32-bit i386 userspace drivers, which had to be manually upgraded to the above mentioned latest versions.
Is the wine required combined use of 32-bit (i386) and 64-bit (amd64) userspace drivers on an AMD platform supposed to be valid and stable approach?
