Git not easy due to network restrictions. I am going to see if 4.8.5 compiler vs 8.3.1 makes any difference. Also going to check and see if any bios settings could re-arrange the IRQ's= to work around problem.

At this point, your best approach would be to carry out a git bisect between those two kernel versions. Or maybe just between 5.6 and 5.7 (I assume that 5.6 is okay, just like 5.6.1, and 5.7 is bad, just like 5.7.1). That would= let you identify the exact commit where the problem started. -- You may reply to this email to add a comment.
