Great that it is resolved :-) As many people are affected and the Stable kernel version still seems to exhibit the problem, I want to ask a question: Are you willing to help out to narrow down as much as possible which version introduced the error and in which is was fixed? Wrt the latter, does 5.14.12-1 still show the issue? Via https://snapshot.debian.org/binary/linux-image-amd64/ you get (easily) get all the kernel versions that were released. If we know a (reasonably) small range of kernel versions in which it surfaced and a small range in which it was fixed, then we could make some educated guesses as to which commit caused the issue in the first place.
