The usual symptom is that I get the radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec GPU lockup (waiting for 0x00682AC3 last fence id 0x00682AC2) [...] kernel message. Each time with the fence being off by one like in the example above. If this change has the potential to fix this issue I think this particular patch should be considered for the current upstream kernel release.
