Warner,
  Every time it gets wedged I have to power cycle it.  I've done that a bunch
in the last few days.  500 times?  Probably not but dozens?  At least.  It does
(did) stay on continuously doing mostly nothing for long stretches when I'm not
using it.  I suppose it could be power.  my recollection is that I only
installed the 8 pin ATX power connector for the CPU not the 8 pin and 4 pin but
the directions clearly say you can install both but you don't need to install
the 4 pin if you have the 8 pin.  I don't really have the option to swap in a
new power supply but I could remove the 6 hard drives so that they aren't
consuming power and leave just the SSD.

Graham,
I don't have a boot environments of 13.0 but I suppose I could reinstall the
13.0 SSD and try.  On the other hand this machine got a new SSD in the last 2
weeks and thus 13.1 was installed because the old SSD with 13.0 on it had
similar problems and I was suspecting at the time flaky hardware with the SSD
being the cheapest/easiest thing to replace.

This was meant to be a build machine and given I can't hit the SSD hard it
makes it almost useless for me.  Builds over NFS (even over 10G ether) are WAY
slower mostly due to the time taken to untar the distribution files.
