I've found and fixed a bug or two in the 53c96 scsi driver (esp0) and
put a new netbsd.quadra kernel up for 040 owners to try out.  There is
no longer a separate netbsd.quadra_dual kernel--this kernel includes
that code and should allow Q900's and Q950's to probe the scsi bus, but
they still can't boot all the way for lack of a console.  There is also
some issue about how to specify the root scsi id (i.e., "which bus?"
since NetBSD won't care if you have scsi ID 4 on both busses (MacOS
does care)).

Do you mean, 'just before checking filesystems'?

That will not happen unless you mount it by hand.  Part of going
multi-user is mounting root r/w and mounting the rest of the filesystems
specified in /etc/fstab.

If the kernel that I've just put up has the same panic/vm fault, please
write down the info the shows up before 'db>' and the output of the 't'
command from the debugger.

SBC scsi is for the folks with the 5380 SCSI chip.  You have a 53c96.
The kernel that Steve put up is probably lacking my most recent changes
to the esp (53c96) driver.

Actually, the first three that you list were the same kernel for a
while.  I've removed all three and put one netbsd.quadra up.

The changes that I've been making have been checked in and should be
available with NetBSD-current (available via sup from sup.netbsd.org and
mirror sites).

Yuck...  Keep it...  ;-)
