The worst case is 1 to N random reboots during buildworld (been there, done
that), leaving the filesystem inconsistent, needing an fsck -y, unless you
trust background_fsck, then finding out it's the hardware, not the OS.
It's easy to find out if the OS panics, by enabling crash dumps. Then you can
still decide whether an upgrade might fix it and you may even get a clue as
to which hardware or kernel subsystem is affected, if the kernel dumps.
I've had a machine where I never got buildworld to finish, tried 4 or 5 times
hoping to get lucky this time...
Reapplying thermal paste to the CPU heatsink made everything work.

Problem with today's modular software: they start with the modules
and never get to the software part.
