Hi, I received no answer at all, so I guess you are very busy.
I know the bug was introduced somewhere between 5.6 and 5.7. If you have an idea of what the source of the bug could be, I'd like to help by testing on my computers, or providing code. I have two computers with similar CPUs (i5-5675C & i7-5775C), and both have the same problem. Basically I'm limited to kernel <= 5.6, right now. I can't boot from a more recent kernel. Thanks, Alex
