There's been a bunch of updates on DRRS in the past year, and I have yet to see a dmesg with debugs enabled reproducing the issue on a recent kernel. We need data before doing anything else. The discussion in this thread is not actionable. For all I know the issue could've been fixed already. BR, Jani. -- Jani Nikula, Intel
