That says the bootblocks are finding the kernel, so the label
should be OK.  It sounds like init isn't finding a console.
I presume  booting single-user (boot 3/rz?/netbsd -s) fails too

What does 'ls -l <pmaxroot>/dev/console' say on the NetBSD/i386
machine?   How about
	ls -l  <pmaxroot>/dev/rz0*
	ls -l  <pmaxroot>/dev/rrz0*

(substitute the scsi ID of your pmax root disk for 0 in the above.)
