Subject2.0.0/2.0.25 oopses with buslogic 956C and two 4G seagates ...

Here is the oops from my buslogic scsi machine.

Why not? Isn't it supposed to be? That is what the bios setup says!

I was wrong. There is no soundblaster. Apparently it is planned for the
machine but is not yet in the box (I had just to bend down and take a look).

I am now using the 2.0.23 buslogic.bin slackware boot disk downloaded
from your home page (nice work!). Same result, but more error messages.
I'll type out what I can now see on the machine next to me ...

This should be interpreted via your buslogic.bin System.map ... it does not
seem to be on the diskette. Hang on - I will search your web pages again.
Nope it's not there. Sorry - I can't do any better than this. I hope you can
match the assembler some other way.

I would guess that the fault is when init can't be started because there is no
disk! Can't we die gracefully? I am on a ramdisk. The stack seems to be
repeating. Maybe something called itself recursively and went out of the
stack "segment"? Would that be a gpf?

To rub salt in the wound, here is the FreeBSD dmesg for this machine (again).
Can anyone give me a clue?
