Hi Sven,
Thanks for the update. I'll be happy to assist in testing if you need
a volunteer with a PowerMac7,3 dual G5. I'm looking forward to
testing the new d-i for my final installation.
I debootstrap'ed a Debian install on my G5 yesterday using a Gentoo
livecd, and I could run Sarge in a chroot so I could work on a patch
myself. Paddy de Burca gave me the confirmation that the problem was
related to the 970FX on the PowerMac7.3 platform of my new hardware.
So, though you've probably got it all from benh, here is what is
working for me right now. This is a patch against the clean Debian
2.6.8-10 kernel source package, which I then compiled with
kernel-package using the debian 2.6.8-10 kernel and 2.6.8-6 powerpc
patches using the power4-smp config (after fighting off #220389 in
kernel-package for a whole afternoon, but that is a different story).
I'm sure you will recognize each patch (I think all three are from
benh) so I'm not describing them.
I have not compiled a kernel in 3+ years, and it's been 5+ years since
I worked on ppc firmware, so I'm feeling quite pumped up even if all I
did was copy patches in a chrooted sarge install ;-) And my new
Christmas present is now running *Debian* on all CPUs <grins>
Cheers!
Shyamal
