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.
