Okay, I have a clue. Now what to do with it?
I found "general protection fault" and "Oops" messages while trolling
through the /var/log/kern.log* and /var/log/syslog* files. Here are the
ten I found in the kern.log* files over the last ~30 days and the following
RIP: lines that indicate where the problems occurred:

I have a sinking feeling that my CPU is bad, but how do I test it to prove
that is the case? I've seen mentions of running programs (xxx Sieve xxx?)
but I don't know what they were, where to get them (apt-get xxx?), or if
there's parameter settings to address for best testing.
OTOH, it might be the RAM, but I'd have to take Myth off-line for more than
12 hours (max time I've tried so far to run memtest86+) which didn't turn
up any errors.
Any suggestions? Need a bigger piece of the log for one/several/all of
these?
