Trouble with IBM RS/6000 43P-140

Hi.

I have some 43P-140 machines. I tried to netboot one but the machine
refused to load the boot image. I tried the sysinst and the generic
kernel image. The images are build from -current about a week old.

I tried to load the image via floppy but the kernel crashed very early
in startup:

Is someone successfully running NetBSD on a 43P-140?
Any ideas about net booting? It is quite hard to debug a crashing kernel
when I have to write a boot floppy for every boot attempt.
