Oooh...that's interesting. It looks like it actually gets all the way
through head.S. The PROMLIB line is from the call to prom_init() in
head.S just before it finally calls start_kernel(), and the the "ARCH:
SUN4U" is in setup_arch(), which is well after head.S has jumped to the
main kernel.
Why it's looping with prom_init(), I'm not sure. Maybe the prom cif
handler and stack aren't getting setup properly. Dave, any ideas?
