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
0x0000000000000002 last fence id 0x0000000000000001)


My system has:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI RV620 [Mobility Radeon HD 3400 Series]
