The errors associated with acd0 were from an attempt to determine if the
problem was just SCSI related. I normally access the device as cd0.
My bug submission includes many lines associated with cd0 i.e. those
starting with (cd0:ata1:0:0:0).
Looking further into the cronology of the problem, it appears my write
to DVD completed *before* the first (cd0:ata1:0:0:0): READ(10). CDB: 28
0 ff fd 0 0 0 0 1 0 error was reported.
After a complete powerdown, and restart, of the system I was able to
mount cd0 so it appears the hardware got into a spurious state. Whether
that's the fault of poorly designed device firmware, or a buggy driver,
frequent power-cycling on a system that is a server is not desirable.
