I don’t know when it started, but with recent 4.6 kernels and the drivers 367.27 and 367.35 i’m having a horrible time when running 3D applications - roughly 3 crashes a day. It may have started when i was still on kernel version 4.5, but i’m not sure.
still happening - i’m gonna try 364.19 (which i skipped before)
unconclusive - with 364.19 I had my earlier experience of the UI freezing for 60 seconds and coming back, until finally I got the “GPU has fallen off the bus” again. It could be that a kernel with BFS and BFQ patched in is more susceptible, but this time I observed it with the vanilla kernel.
