Starting from 5.5c none of the versions have got along with linux kernel 5.11, including this one. On 5.5c only first GPU was hashing, on this version it seems like everything starts up properly but then within 15-20 seconds, hashrates start going crazy, fluctuating from 8 to 31 (all polaris GPUs) and the whole OS gets slowed down to 0.2 FPS.

Is there maybe something that needs adjusting on my side or is compatibility still in the works?

I'm asking because kernel 5.12 is right around a corner and it seems like at this pace the gap is only going to grow.
