Description Klein Kravis 2020-12-26 21:23:44 UTC 
I updated to Kernel 5.10 and have had some issues. Most of the time it doesn't even boot due to workqueue lockup, but when it does the performance is severely degraded. I have decided to stay on Kernel 5.9 for the time being but would like to be able to update.

Could you check the workaround suggested in
  https://apibugzilla.suse.com/show_bug.cgi?id=1180344#c16
?

In anyway, please give dmesg output with the workqueue lock up.

This workaround fixed the issues
Comment 4 Klein Kravis 2020-12-28 22:24:51 UTC 
Disabling logging fixes this bug. This is a rather severe bug and I will be proposing it as a Final Blocker for Fedora 34
