It is a server, but a home file server.  The raid card has no battery
backup, and in fact has been flashed to pure HBA mode.  Actual
RAID'ing is done at the software level.

The system has eight total drives: two SSDs in raid-1 for the OS, five
3.5 spinning drives in RAID-6, and a single 3.5 drive normally used
for mythtv recordings (though mythtv has been stopped for a long time
now to try to debug the issue).

Yes, I updated everything except packages beginning with "l" ("el" /
lowercase 'L') due to that generating a number of conflicts that I
haven't have time to resolve.
