I have observed this randomly on the G5 ... sometimes, if I try again,
it works... it's very very odd. There is some kind of race maybe with
async startup ? Or a problem with the vfs path walking ? It's certainly
not easily reproducable for me, it goes away from one boot to the next.
It also happens sometimes with an initramfs (cpio), it's not specific to
ext{2,3,4}.

Hrm, did it used to boot ? Can you do printenv in OF and tell me what
your load-base, real-base, virt-base etc... are ?
Might also be worth updating yaboot, debian should have 1.3.16 nowadays.
Cheers,
Ben.
