Well, the advice to install Xkernel first is incomplete.  All you
really need to do is install working RARP and Bootparams daemons
on your linux box (as well as NFS of course).  Most linux users
find it easiest to grab those items out of the Xkernel package.

That's all you need from Xkerel.  There is no need to actually
boot Xkernel, so there is no need to bother setting up the root
partition for the Xkernel client.  Instead, just setup the root
partition with NetBSD/sun3 and skip the other Xkernel stuff.

As you may have noticed, Xkernel is just a stripped-down copy of
SunOS with some server support programs...

Who knows...  Could be a SunOS problem, or bad RAM, or ...

What did it say the console was in the first line of kernel startup?

You may need to change the EEPROM console setting.
