[153104.234724] Run through mcelog --ascii to decode and contact your
hardware vendor
If you it through mcelog as it suggests it wil decode the meaning of the
MCE data and that should give you some idea. Generally speaking MCE
errors are real hardware errors but can certainly be caused by external
factors (power supply glitches, heat etc)
Sorry, of course I ran that through mcelog, but inadvertently attached
the original version.
I've tried the machines with two types of power sources (different
UPSes, line filtering, etc,
and the chassis have redundant PSes), monitoring the temperatures (seems
to be OK,
the CPUs don't go over 30 °C even under load). I have the latest BIOS
for the
motherboard.
But I will recheck everything.
BTW, here's the output from mcelog, I see this occasionally on all four
machines:
