Description rafael castillo 2013-05-22 04:52:57 UTC
My radeon 7770 from msi crashes the kernel at any try to change the freq of the gpu been medium or high profile(is always in low) and dynpm never kicks in whatever you do, it always stay at low.

Attaching image of the crash if you need anything else please include some instructions. Have years without debuging a kernel
