Public bug reported:
Dell Vostro 15 7510
:lsb_release -crid
Distributor ID: Ubuntu
Description: Ubuntu 21.10
Release: 21.10
Codename: impish
Sporadically the laptop does not respond to keyboard or mouse input. The
cursor still shows up. This may be associated with waking up from suspend. I
can still get to a terminal with Ctl-Fn-Alt-F1.
I see this in kern.log at about the time of the issue:
