This is quite plausible, however, this happened about 1/2 hour after
startup, about 3PM, after being off since early morning.  According to
the log, it started back up within 1 minute, although it seemed longer
to me.  The drive actually shut off - I heard it click and then spin
down - and then click and spin back up.  I'd think the drive should not
have gotten very warm in that period of time, and it often has uptimes
of 4-6 days.

Also, as I said in my original post, I was in X.  I don't recall if I
hit a key or not, but it didn't seem as if the mouse was working.  It
came back on after I hit CTRL-ALT-F1.  Also, the screen didn't switch
immediately, but only after the HD came back on.  It almost seems as if
the computer itself had done all this.  While this was all going on,
however, the HD light was flickering normally (for it) as if real disk
activity was going on.

My kern.logs go back to Jul 2.  This is the only instance back to then,
and it hasn't repeated itself again so far.

I just checked my drive.  I have a single HD mounted in the second bay
from the bottom, with nothing below it, and nothing in the next bay
above it.  Thanks for this tip, though, it may prove helpful later.
