The way it fails booting is a bit entertaining: using BootX 1.1.3, it will
show a little more than half a page of messages (arch_exit or similar in
the last), then starts drawing funny color fringes on the screen until I
reset. Using BootX 1.2b3, it locks up after the first six or so lines of
text (before getting to the early console output). 2.3.29 worked fine. Any
ideas?
I think I know what's going on:
- make sure setting the display BAT in arch/ppc/mm/init.c (MMU_Init) is
commented out, this is a hack and need some alignement tricks to work in
all cases. It should already be in #if 0/#endif
Check.

- in arch/ppc/kernel/pmac_setup.c, comment out the content of the
function pmac_progress. (Or change pmac_init() so that it sets
ppc_md.progress to NULL, and set it to pmac_progress only pmac_setup_arch()).
Tried both. I get the arch: exit if I set ppc_md.progress in pmac_setup
arch. Shortly after this output, the color fringe fun starts again.
I'll strip my .config to the bare minimum to narrow this down. Thanks for
getting me this far :-)
Well, I wanted to reply earlier, but unfortunately my telco dropped my
line for two hours and I was thinking about having destroied my modems
until I had a look to my /var/log/messages arghhhh.
What I did: I have both trees living around on my PB. I did a diff
against the linux-pmac-devel/arch/ppc and patched the missing things. I
know a bit dangerous, but it did the trick. It's not only the things Ben
mentioned, also the drawx vs. prom_drawx are necessary I think. So it
boots on an Wallstreet I, AND on an ancient pm7200!!
I may post a patch, but I'm not quite satiesfied with since I don't know
at all what's really necessary. Sorry, but I think it's better not to
distribute a wrong patch.
