Perhaps, but in the case that was actually problematic it was raid0,
not ld1.  ld1 was just the example I used when composing the email; at
that point, there were no raids, so a failure opening raid0 would be no
surprise at all.

Oh-h-h.  I must have botched something when bringing the machine up to
4.0 (odd it would be from -3, though, since I thought I went straight
from 2.0 to 4.0; I must be misremrembering).  No wonder it didn't like
dk0.  I'll extract the /dev/ stuff from the 4.0 distribution and see
what else is wrong there.

It's a production system, so I can't get _too_ experimental, but it
does tend to have hours when it's not doing anything (its primary
function is nightly backup runs), so I can probably get at least a
stack trace, maybe even a kernel coredump.  (Hmm, I wonder if mounting
a filesystem -o sync and putting a ktrace log there will give me a
useful trace up to the point of panic...I should experiment.)

Thank you very much; you've pointed me in some most helpful directions.
I'll look at this again tomorrow (it's at work) and see what I can see.
