I am trying to upgrade the bunch of Sparc/SLC stations to -current and
run into kernel panic during boot. After the kernel correctly tested
MAXTOR drive for sd0 it tried to test sd1 and paniced on zero
division. I could try to write down more output but I hope that
someone would recognize the problem. I have the same problem with
-current (May 25) kernel and the kernel from netbsd.org:arch/sparc
(apparently, May 2 build) My previous (working) kernel was March 20, I
am not sure I had sup running then. The kernel from -current sources
works fine on other (diskless) machines, I had to specify only
mount -t nfs -o rw,-2 -a
somwewhere in /etc/rc. Below is the SCSI-related output from the working
kernel. I did not worry much till now about "expected bus reset" and
"illegal request" messages, maybe they were the early signs of
trouble? 

The hard drive and the tape are in ugly external box, SCSI id set to
3=HD, 4=tape.
