Drat, spoke too soon.

soft updates on, dma off. Hang (in kde) followed by black
screen and reboot. This time vinum died on startup and I
had an anxious 10 minutes starting all the subdisks.

I'd better test the memory. Then I'll try booting from
the backup root in case ad0 is toast. I guess duff hardware is
looking more likely.

I noticed some UDMA errors when rebooting from single
user, which failed to sync 1 block. Of course these scroll
off screen too quick to be readable, but the "head parking"
noise was again apparent. APM is disabled.
