Saw the same error and after reading this thread, reverted the

Commit 2d6cc7296d4ee128ab0fa3b715f0afde511f49c2.

drm/radeon: use async dma for ttm buffer moves on 6xx-SI

and the problem is gone. In my case, it is a solid hang right after
system switches to vga. I was able to login on console once or twice.
But dmesg showed the same message reported in this thread:

[ 35.812085] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec
[ 35.812091] radeon 0000:01:00.0: GPU lockup (waiting for

My system has:
