Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

I noticed a while ago that there were some "bad" sectors on the disk, and
at the time they were under the swap partition if my math was correct,
and the box never swaps so it wasn't a problem.  I don't know if
the errors above are the same ones I saw earlier or not.

There were no read or write errors on the console prior to the panic
earlier today.  In fact the previos output on the console relates to
the last reboot for a software upgrade (fixing some packages) 11
days prior.  The only thing in logs going back to November relating
to ad1 are boot messages.

Thanks,

Gary
