i'm the only one in the office running CURRENT, and since it is
hanging more than 5.1 was, i told everyone else to wait before
upgrading. but a coworker (with different hardware [single
processor], but also AMD-based) does get hangs like mine.

i've checked the cpu temp and it is fine.

so i should try running with it off the UPS? the power supply should
be ok. fwiw, the coworker who also gets hangs is *not* on a UPS. it
could be a building power weirdness (which is why i plugged into the
UPS to begin with)...
would rebuilding the kernel with INVARIANTS or WITNESS help at all?
