g4 hang

[carlos duarte]

i just tried the 'freebsd 6.0 for ppc' CD on a old mac g4, it crashed on
boot. i don't recognize the model, but here's what it spit at me:

KDB: debugger backends: ddb
KDB: current backend: ddb

fatal kernel trap:

exception = 0x4 (instruction storage interrupt)
virtual address = 0x3d8f40
