Linux 3.0 fails to boot _very_ early on my Powerbook G4. See the
yaboot/OF screenshot:
http://bues.ch/misc/linux-3.0-pbook.jpg
Linux 2.6.39.2 boots fine.
Does somebody have an idea?
The config can be found here:
http://bues.ch/misc/linux-3.0-ppc-config
It's mostly equivalent to the working 2.6.39 config. I enabled
early OF console, but that didn't help to show better error messages.
The machine is a:
cpu : 7447A, altivec supported
clock : 1499.999000MHz
revision : 1.2 (pvr 8003 0102)
platform : PowerMac
motherboard : PowerBook5,6 MacRISC3 Power Macintosh
detected as : 287 (PowerBook G4 15")
pmac-generation : NewWorld

Interesting, that's before it even kills OF. Are you booting a zImage or
a vmlinux ?
It might be also useful to compile yaboot with debug output enabled to
figure out where the kernel is loaded so we can try calculating where
exactly it dies if it's a vmlinux...
Cheers,
Ben.

I'm booting zImage.pmac.

Hm, I guess I could probably try that.

Ah that might make it easier... I don't remember where it links, can you
show me the program headers out of readelf -a of the zImage ?

As I recompiled stuff, here's the current failure log:

And this is the corresponding readelf output:

Hrm.. the faulting address is outside of the zImage. Odd.
Can you try loading a plain vmlinux instead ? (feel free to strip it).
yaboot 1.3.13 might not be the best one to load a real ELF ...
On my side I'll dig one of my old powerbooks and see if I can reproduce
(I generally tend to netboot the zImage directly, but it needs to be <
4M for that to work due to Apple OF limitations, or use yaboot with plan
vmlinux which exercises a different code path within yaboot).
Cheers,
Ben.

The plain unstripped vmlinux boots fine:
mb@maggie:~$ uname -a
Linux maggie 3.0.0 #3 PREEMPT Sun Jul 24 11:51:30 CEST 2011 ppc GNU/Linux
Is there something going wrong in the uncompress trampoline?

I reduced the image size, so that it's way less than the
2.6.39 kernel size (old is 2.6.39. a is 3.0)
-rwxr-xr-x 1 root root 5.6M Jul 24 12:16 /boot/linux.a
-rwxr-xr-x 1 root root 6.3M Jul 23 20:50 /boot/linux.old
But that didn't help. :(
I'm currently trying to bisect it, but that turns out to be hard
due to various compile issues and stuff like that...

Perhaps your image is getting too large?
