For the past several days (the first time being on Dec 2 as shown) I've been
seeing the following messages popping up:
Dec 2 12:09:11 morden /kernel: wd0: interrupt timeout:

The system will completely hang for several seconds - no process
activity, no disk activity, nothing - then the drive in question makes
the "powering up" sound it does when I first power up the machine, the
error appears on the console and activity resumes.
Can anyone shed some light on what's happening here, specifically,
whether it's a hardware problem with the drive, or a driver problem with
FreeBSD?
Here is the output of dmesg:

Rincewind looked at the boots, with suspicious recollection of the trouble
there had been with the University's prototype Seven League boots. Footwear
which tried to make you take steps twenty-one miles long imposed unfortunate
groinal strains; they'd got the things off the student just in time, but he'd
still had to wear a special device for several months, and he still ate
standing up. -- Terry Pratchett, "Interesting Times"
