I will play more with 5.5 before closing the issue, but at the moment it seems to be fixed. Before I started digging which commits introduced regression I tested my system with (then) latest stable kernel-5.4.2-300, but I see your changes are only in the 5.5 line :). Big thanks Ilia for your help to pinpoint the problematic commit. Marcin
