hallo dear linuxppc kernel developers,
i'm looking for some tips to use a modern linux kernel on my old
Pegasos1 G3 600MHz (IBM PowerPC 750Cxe).
The last working one is 2.6.16.x with arch=ppc.
a picture of the screen when it freezes loading a modern kernel:

thank you,

Hi,
For what it is worth, I can boot 2.6.36 on a PowerMac 8600 with a
750GX processor in it. I have to compile the kernel with gcc 4.1.2.
Figuring out why 4.3.5 won't work is ... a work in progress (maybe an
exorcism will help?).

hi Kevin,
thanks for your suggestion. I just tried but it doesn't work for me.
I've the same freeze also compiling with the old gcc-4.1.2.

ok, it seems that no one is interested to fix Pegasos1 G3 600MHz support.
But if someone is capable (i don't have this skill) here what it
happens reading from serial debug console untill it freezes with
linux-2.6.36.4

What is the last kernel version working on that machine? If you have a
working kernel and can build kernels, you could try bisecting to
identify the change that led to that. Perhaps then someone could have
some ideas.
With kind regards,

I don't know much about the Pegasos OF, but did you give GRUB2 for OF
a try? Maybe it can boot a newer Linux kernel, if it is not a device
tree related problem.
On the other side you mentioned this workaround in
arch/ppc/kernel/prom_init.c to me some time ago:
unsigned long __init prom_init(int r3, int r4, prom_entry pp) :
> node = call_prom("finddevice", 1, 1, "/");
> rc = call_prom("getprop", 4, 1, node, "model", model, sizeof(model));

Can anybody comment, if this "broken translate method in the OF" would
still be needed for arch/powerpc?

Well, since this is long dead hardware not produced anymore, i don't see how the
OF could have unbroken itself by moving to powerpc.
It has been age since i looked into this, but to the best of my knowledge (and i
wrote the above code or at least the earlier versions) it should be still broken.
But YMMV, ...

Any idea then, how the workaround can be ported to arch/powerpc/ or if
there is a better one available?

Sorry, it has been years since i looked these parts of the linux kernel, so i don't really
know how the arch/powerpc code handles this differently. Your best guess is to hunt for the
code yourself, and find the place. I don't remember though if debugging at that time is
easily possible though.
Friendly,
Sven Luther

if chrp support doesn't anymore include Pegasos1 it could be nice to
remove all that dead code. Albeit it's fun that nobody cared about for
it during the ppc=>powerpc switch as Pegasos1 was retired in 2003
and linux-2.6.17 was released in 2006... about three years.

Also, the Pegasos2 OF implementation corrected these issues.
Notice that 2006 was also the year that debian sabotaged all powerpc work,
and had me expulsed because some people in the debian-installer team didn't
support technical critics and had more political pull inside debian than
myself. This happening after almost a decade of me giving my time to debian,
i kind of lost interest at that point, and nobody stepped up to take over my
work.
And on top of that, Franz Pop commited suicide last year, which could possibly
have been avoided if debian's leadership would have showed more maturity and
responsability back then.
Sorry for the off topic rant, but this is something which did take a really
long time for me to get over, and i believe that the debian folk are still not
ready to let it go. I am still censored on debian mailing lists today and probably
banned from irc channels.
Sadly,
Sven Luther

i'm not an expert but from a quick logs comparison I saw two times the

Maybe it's an usefull observation.

Well, I never put my hands on an OpenFirmware machine, but I could
imagine that this is an image loading problem.
Various PPC Linux related websites suggest to set a different load base
for the kernel image on Pegasos machines:
setenv load-base 0x4000000
Does that work on the Pegasos1?
BTW do you get any debug output from a recent kernel on serial port
(with udbg)?
regards,
Gerhard
