[OBSD] What the **** is this?

After having moved to a new house, I plugged in my HP 712/80 running
OpenBSD 3.3/hppa. Here's what happened:

[snip initial messages]
sd0: drive offline
osiop0: osiop_select while connected?
osiop0: target ID 06 reselect nexus_list 0x0
panic: unable to find reselecting device
Stopped at      0x1ae99c:     break 0.5
RUN AT LEAST [bla bla bla]
ddb> ps
  PID PPID PGRP UID S FLAGS   WAIT COMMAND
*   0   -1    0   0 2 0x80204      swapper
ddb> trace
[snip 30 or 40 lines of output]

Any idea what's wrong (and how to fix it)?

I have the trace output right here on paper, so holler if you need it.
