kernel panic

[Stefan Krüger <skrueger@xxxxxxxxxxxxxxxx>]

hi folks,

situation: dragonfly iso image downloaded, installed on a scsi disk, 
everything went fine, then reboot and, well, see for yourself

kernel is 2CSNAP-20040725-2330-GCC2.iso.gz' GENERIC

[...]
Waiting 15 seconds for SCSI devices to settle (<- last kernel msg)
Kernel trap 12 with interrupts disabled

any help appreciated :-)

PS: I had to write everything down by hand, I hope I've got all numbers 
right.
