Hi Sven,

I rebuilt a ppc64 kernel with the Debian source package with exactly
the same config as 2.6.12-1-powerpc64 from sid.

I turned on the udbg console for pmac in setup.c as benh suggested. I
basically turned on debug in all the files in arch/ppc64/kernel and
the kernel still seems to halt at the same point with the following
output towards the end (copied by hand)

<quote>
time_init: decrementer frequency 33.333333 Mhz
 -> set_preferred_console()
stdoout is /pci@0,f0000000/NVDA,Parent@10/NVDA,Display-B@1
No preferred console found!
smp_core99_probe
smp_core99_kick_cpu
smp_core99_kick_cpu done
smp_core99_setup_cup 0 done

2.6.12-ppc64
</quote>

(the -ppc64 suffix is what I passed to make-kpkg, probably a bad
choice but....).

I've not had time to determine if this console message from setup.c is
important, and I don't have the knowledge to know on sight (though it
certainly sounds like a problem)! But that seems to be the only
additional debug traces that seem relevant. As far as I can tell the
last line is coming from the pseries set up code where it prints out
UTS_RELEASE.

Any ideas? I can continue on this on the weekend if you can suggest a
way forward (had one too many Friday night beers to keep going right
now ;-)

Finally, do you want to merge this bug with #319986? It does seem like
they are both the same even though the machines are slightly
different.

Cheers!
