--- Comment #15 from Christian König deathsimple@vodafone.de --- (In reply to pstglia from comment #12)
It was reported by one member that patch is causing stability problems for HD 7950 (TAHITI). I've attached the full dmesg. The volunteer tested the patch with Mesa 10.5.4 and 10.6 RC1. Same behavior in both cases according to him
The mesa version is uninteresting, but what kernel version are you using?
Older kernels have stability problems when you unmap the BO VA. That's why we don't use it in mesa by default.
