Comment 33 for bug 1942935

Yeah, that's the same issue as this one. The issue is the raid is doing a consistency check (mdcheck) and is transitioned to an "idle" state and hits a deadlock that causes all I/O through the md device to block. The workaround is to change the array state back to active.

I made the changes in #5 almost a year ago and no problems, before that it pretty much hung almost every single month when the scheduled consistency check was triggered ever since upgrading to 20.04.
