Hi!
My window manager stopped responding. I was able to recover machine using sysrq-k.
I started writing nice report, when session failed second time. And then third time on next attempt.
Any ideas?
Do you know when the regression started? There have been significant code changes regarding the sound buffer management, and it's merged in 5.6-rc1. Other than that, I have no idea yet.
It is first time I seen this. I may have missed the oops in the logs, but I would not miss marco dying.
So... AFAICT this was not there in -next20200505 or so.
Best regard, Pavel
