A couple of days ago, I sent this email to Ben, but so far I have not
received a reply to it.

I decided to try to compile my own kernel on my SPARCstation
2 running NetBSD/sparc, and this worked, but the kernel I made did not
get very far. Now I am building a new FOURMEG kernel to see if that
works.

The sources I am building from are from yesterday, so this will also be
a test of whether Ben's patches to the PCF8583 probing works on my R140.

Unfortunately, I have to go to work, and I will not be able to check
this until I get back around 7 pm, but I will let you know how it works.

TIA!

OK, I found out that I could set up my router to forward the dhcp
requests to another box, and this is now my ss2. Everything seems to
work fine upto the point where it tries to mount the filesystem. Then it
fails:

root device: ea0
dump device:
file system (default generic):
root on ea0
cpu.dumpconf: Doing ...
nfs_boot: trying DHCP/BOOTP
nfs_boot: DHCP server: 192.168.169.180
nfs_boot: my_domain=thomassen.priv.no
nfs_boot: my_addr=192.168.169.177
nfs_boot: my_mask=255.255.255.0
nfs_boot: gateway=192.168.169.168
root on 192.168.169.180:/home/export/r140
panic: Reset handler called. Branch through zero?
system halted

Any ideas why?

I've done what's given at:
http://www.netbsd.org/Documentation/network/netboot/files.html

I have also checked the /var/log/messages and /var/log/authlog, and
everything else looks fine.

TIA!
