(Get the code!)
Since updating to kernel 5.15 in Ubuntu LTS 20.04, I got several stability issues with my AMD RX 6600 XT graphics adapter. I upgraded to LTS 22.04 with the hope to be able to get more recent kernels, but the HWE kernel is still stuck on 5.15, while I would expect it to be at least on kernel.org's recent stable kernel, 5.19.3 as of now.
These are the bugs that seem to affect me and other users of more recent AMD GPUs:

If you read the bugs, you find that people report kernel version 5.17 or more recent to fix them, which I can confirm: I started to run the Ubuntu OEM kernel ( 5.17.0-1015-oem ), and thus far got a 100% stable system.
So, I guess these problems will be solved with the next HWE kernel, scheduled for October. However, for current Ubuntu 22.04 or 20.04 HWE users, there is no supported solution to get a stable system with various amdgpu adapters.
