# DF-4241 kernel panic (raw serial console; the panic message and the rig's
# final kprintf interleave because the CAM SWI panics while the ioctl
# thread is still printing -- both are authentic concurrent writers).
#
# De-interleaved, the two streams read:
#   [dptrig] DUPALIAS: lock released -- the second xpt_done() already
#   re-enqueued the completed CCB on sim_doneq; camisr_runqueue() is
#   expected to detonate on the corrupt list now
#   panic: Bad link elm 0xfffff801185f0ec0 prev->next != elm
