Is the behavior affected by having the disk loaded or ejected?  I have had
boot problems (hangs though, not panics) when the zip disk is loaded
during the boot.  With the zip ejected, it boots fine and I can later
mount the zip disk.  (This is a P550, Generic-45).

Bill and Colin have already suggested trying an SBC kernel, which you
certainly should, but it may be more complicated than that.  I happen to
have a HDD that really cannot stomach the SBC driver.  I have found,
however, that I can still use the zip, though I might add with
considerable caution, using the ncrscsi driver.  I would suggest first
assuring yourself that your HDD works properly with the SBC kernel, and
once you are confident of that, start experimenting with the Zip.

Good Luck,
