lockups that I experience since some time every now and then.
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.

No this patch doesn't. This patch is all about getting proper sync btw different rings.
Sorry for the deception.
Cheers,
Jerome
