I got the biodone already bug while developing the Atari SCSI-driver (no, the
Atari release is not yet available). The cause of it was that multiple
instances of the SCSI-interrupt routine were running. I don't know if this
is possible on the Mac. On the Atari I had to remap interrupts to their proper
level because they were all coming in at the same level. I allowed SCSI
interrupts to happen at an ipl >= splbio instead of > splbio. When the
equal sign was removed, the panic's disappeared. 
I hope this helps in finding the problem.
