Hi Linus,
A change to scsi.c in 1.3.66 (perhaps in 1.3.65) broke the scsi scan pass,
generating the following on boot (logging to /usr/adm/messages
got screwed up as well in the process). Things were ok in 1.3.64.
This is on a P586.
Hard media disks get marked as unknown type 31,
and the MULTI-LUN pass goes through all phases on each
disk target.
I do have a NEC CDROM drive that is multi-lun, but the hard disks were
passed through all LUNS as well.
Later on in the boot e2fsck complained about the hard drives, but didn't
fix. On the next boot they were marked dirty, and forced into a clean
state.
The change in scsi.c that created this problem was:

(Don't know why the addition of ILLEGAL_REQUEST to the test mask was
breaking it).
Reverting back to the 1.3.64 version of scsi.c fixes it all up properly,
and also allows proper logging to /usr/adm/messages:
Here are the log bits for the broken scsi.c in 1.3.66 (pine might wrap
these lines):
