System: NetBSD chekov 1.6.2_STABLE NetBSD 1.6.2_STABLE (GENERIC) #1: Fri Apr 23 15:51:29 CEST 2004     root@chekov:/u1/branch-1-6/build/sparc64/obj/sys/arch/sparc64/compile/GENERIC sparc64
Architecture: sparc64
Machine: sparc64
Ofwboot on the netbsd-1-6 branch seems to fail loading some kernels,
the issue seems to be related to the kernel data+bss size.
Current's ofwboot also fails to load the same troublesome kernels.
Sparc64's GENERIC kernel is loaded fine but a simple simple addition
-see below- to this kernel config makes it failing.
Also notice that a stripped and otherwise failing kernel does boot.
# cd /usr/src/sys/arch/sparc64/conf
# echo "pseudo-device vlan" >> FOO
# config FOO
# cd ../compile/FOO
# make depend && make
# make install
# reboot

You should then see something like:

Executing last command: boot
