Public bug reported: Probably related to this Bug https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.6/+bug/1876567
My server gets totally unresponsive (keyboard, no network, num lock doesn't work, ...), even sysresq does not work most of the times. The Problem seems to be related with nfs clients accessing the server and an windows 10 kvm with gpu passthrough is running. The system does not even create an kdump or logs anything interesting in journal which may give some hints. Thank you in advance, hope we finally find a solution.
