[Bug 1925215] [NEW] System completely freezes and requires reboot

[Tanner McLoed]

Public bug reported:

The OS spontaneously froze whilst doing some work (firefox, VMs). I
can't find anything suspect in the logs at this stage. I will keep an
eye out for this issue but would like advise on what to check for, any
tools I should install and commands to run when it crashes again.
