Supermicro motherboard X5DPR-8G2+

It has been running 4.11 solidly for almost 2 months now.

Some more info on the system is here (about a problem experienced
on the same system):

I applied that towards the end of January.  Pretty sure anyway,
memory is fading.

We were running:

  FreeBSD 5.3-RELEASE-p5 #3

when we abandoned ship.  If memory serves, I rebuilt the kernel
only (not the world), when I applied those patches.

I have left the department that owns the server now,  but
I've asked them to followup to this mailling list when they
continue with the diagnosis.
