I see. What should I test?  that  the  nominal  voltage  is  proper  and
stable?  However,  if  that  was  the  case,  the  machine  would   fail
erratically, I believe, while it appears to fail quite deterministically
(upon an apt-get upgrade, for example).
Basic parameters are DC voltage on load, and AC ripple on load. You'll
probably need fairly decent test equipment to see the switching frequency.

Or a known good power supply ...

Yes. Which is why, with respect to everybody and with appreciation of the effort of the core developers, I also suggested testing with a known good distro.
