I poked around a bit and found that the actual error message appears
to be coming from scsipi_interpret_sense() in sys/dev/scsipi/scsipi_base.c.
It looks like the data being passed to scsipi_interpret_sense() is all
zeroes.  

I built a kernel configured with SCSIDEBUG and a hack to scsiconf.c so that
all devices get their debug flags set to DEBUGLEVEL.  I've included that
boot log at the end of this message, minus the part where esp0 probes
all targets and finds nothing.

I've poked around in the scsi code for a while, but I haven't been able to
make much sense of it yet.

Here's the full boot log:
