Public bug reported:
I've been getting freezes on Ubunyu 20.04 on my Dell Latitude 7420
laptop with a secondary display connected through a WD19 Dell dock. I'm
on the supposedly-certified 5.6.0-1048-oem kernel, have tried 5.8 and
5.10 without much success (other types of freezes). Some freezes lock up
the machine hard with no way to ssh in or check anything and no logs.
The one below I was able to ssh in and dump dmesg, rebooting via ssh
froze and I had to do a hard reboot.

Bug description:
I've been getting freezes on Ubunyu 20.04 on my Dell Latitude 7420
laptop with a secondary display connected through a WD19 Dell dock.
I'm on the supposedly-certified 5.6.0-1048-oem kernel, have tried 5.8
and 5.10 without much success (other types of freezes). Some freezes
lock up the machine hard with no way to ssh in or check anything and
no logs. The one below I was able to ssh in and dump dmesg, rebooting
via ssh froze and I had to do a hard reboot.
