Had this a few more times. Took some time to rummage in the journal and
found this just before it happened.

Title:
System hard locks up intermittently
Status in linux package in Ubuntu:
Confirmed
Bug description:
My T450 main laptop is generally left on all day and night. I
sometimes suspend it when moving around the house, but it's often left
on all the time. Sometimes when I go to start work in the morning
there's some corruption on screen and the laptop won't respond. I
can't REISUB or ssh in.
This has happened a few times since clean installing 20.04. Previously
I was on an upgraded-to-20.04 install and don't recall it happening
there. The other obvious difference is I'm now running ZFS which I
wasn't before. :S
