I'm sorry to hear about the troubles you've seen. I did hedge slightly with 'may' :p I've had the exact opposite experience; from way back since the 4870 series was common to now with RX6000, AMD has been great for me with Linux. More systems than I can really count, Intel/AMD have been great - while Nvidia, not so much. Most recently I've not used the 'auto' method of DPM (mentioned in that issue). I've deliberately set this to 'manual' since at least picking up RX6000 for undervolting/overclocking. Perhaps this is part of why I've been so pleased. I'm curious on the software levels you run - what distributions do you tend to prefer?
