I am having a problem getting NetBSD 1.2 installed on a sparc ipc.

I have set the two OpenBOOT variables as requested by the INSTALL doc

I then installed the miniroot-12.fs.sun4c onto sd0b and did 
a "boot disk:b netbsd -s" I did this in single user after a fresh
reboot.

The system comes up and the kernel boots to:

root on sd0b
WARNING: clock gained 152 days -- CHECK AND RESET THE DATE
Preserved 9630 blocks of miniroot leaving 17546 pages of swap

At which point it hangs, I can still STOP-A to reboot.

Any suggestions on what might be going wrong?

Chris.
