Alright,
I'm trying to get my G4 off of OS X for its primary OS. I have a working Debian install on a 40 GB IDE drive (kernel is custom 2.6.26). I am trying to update the kernel to 2.6.39.1, but I cannot get the new kernel to boot.

I'm sure I should post this elsewhere, but I've had good luck here with fellow PPC Mac users before.

Anyway, when I point yaboot to my new kernel, it prints out about two lines (the usual "Elf32...." blah blah blah), then flashes to a white screen that looks like open firmware. The only thing this screen says is:

Code:
done
found display     : /pci@f000000/NVDA,Parent@10/NVDA,Display-A@0, opening...
And that's it. System hangs from there...

I'm not sure what to make of it. I feel like the nvidiafb should take over, and I've got it compiled in the kernel as a module (just like the working 2.6.26 kernel on this machine), but nothing happens. I've never seen the white open firmware screen outside of..well, open firmware.

I can post any files necessary...until then I'll just keep fiddling with the kernel configuration, rebuilding and trying it out.
