Crash information

One segfault I observed was due sctx->b.dma.cs->current.buf being NULL in
cik_sdma.c:377 (the first radeon_emit call in that block). Attached is the full
stack trace and some additional info.

Another crash didn't have any Mesa stack frames. Not sure what's going on
there.

I played a bit using amdgpu-pro 16.30.3.306809 (on top of the upstream 4.7.0
amdgpu kernel module), and there were no crashes or lockups. Also, the game
runs noticeable faster on the blob :(
