This issue must be strongly linked with the Murphy Law.
Got another compile error when y a add CONFIG_6xx=3Dy
to my kernel config.

  LD      .tmp_vmlinux1
ld: arch/ppc/kernel/idle_6xx.o: No such file: Aucun fichier ou
r=E9pertoire de ce type

Unfortunetly i've got to move (some trip for my study) and i won't be
able to have access any g5 or PPC970 with linux on it until i came back
friday or saturday. Anyway i may access my mail until then.

Does this disable_6xx_mmu function do something that we should really
have on PPC970 ? I hadn't get enought time to look at this function and
understand it.

By the way, even if i pretty sure this is not related, my kernel is patched
with one of my patch (i posted it on this mailling list) that add support o=
f U3
agp bridge on G5.

This patch only affect few file and if i remember well, i have tested witho=
ut
it too with no success.

Files affected by my patch pciids.h, uninorth.c(char/driver/agp),=20
uninorth.h(asm-ppc&64). and some change in Kconfig of (char/driver/agp)

One strange things is that no one except me report error on compilation ?
No one use linux with g5, am i alone :) ?

best,
