https://bugzilla.kernel.org/show_bug.cgi?id=78221 --- Comment #20 from t3st3r@xxxxxxx --- 1) About 3.15 + patch: I gave it a try and it took quite a while to get opinion about it. Overall it is quite stable and survives about several days of run of problematic load. But eventually GPU still could encounter crash. Intereating thing in this occurence I caught is that regardless of scary message about failed DPM resume, GPU seems to be operable after successful recovery. I got couple of similar crashes as well within a week. It looked like this: ===cut=== [815114.959250] SysRq : Emergency Sync [815115.071974] Emergency Sync complete [815116.935547] radeon 0000:01:00.0: ring 0 stalled for more than 10082msec [815116.935556] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000007f39f60 last fence id 0x0000000007f39f5f on ring 0) [815116.935564] radeon 0000:01:00.0: failed to get a new IB (-35) [815116.942472] radeon 0000:01:00.0: sa_manager is not empty, clearing anyway [815117.134467] SysRq : Keyboard mode set to system default [815117.500079] AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x0018 address=0x0000000080406640 flags=0x0000] [815117.500092] radeon 0000:01:00.0: Saved 6061 dwords of commands on ring 0.
