Inspired by Scott ("Getting the ol' Macintosh LC475 modernized") I pulled my
LC III out of the closet and tried to follow along to get up to date. I
untarred Thorsten's filesystem to /, got the initrd from
http://zigo.mirbsd.org:8080/t/initrd.img-3.10-2-m68k and the kernel from
http://www.freewrt.org/~tg/f/vmlinux-3.10-2-m68k.gz, and since Penguin said
it didn't have enough memory (I have 36mb total) I put the files on disk and
booted an emile floppy which was able to load. The boot hung early, however,
and sat here for over an hour:

The last line is about disabling the boot console, long before macfb is
initialized, so there's a "black hole" in between.
Can you try to add "keep_bootcon" to the kernel command line? That
should keep the boot console alive. It may conflict later with e.g. macfb
and the freeing of init memory, and crash horribly there, but it may give
some valuable information about what happens during the "black hole".
This was valuable, thanks! I set the parameter and it showed that I'm
getting a kernel panic for lacking an FPU. I started this project after
the 2.2 kernel was throwing errors for unimplemented FPU instructions,
so this doesn't surprise me. (I'm not the Mac owner so I can't vouch for
factory config, and the PDS slot currently holds a Farallon ethernet card.)
I just read through last month's FPU emulation discussion and I
understand the emulation isn't in the kernel I'm using - perhaps I can
find one further back? I'm not opposed to building myself a kernel
however I haven't ever cross-compiled one and haven't built on x86 in
four or five years, so I'll probably ask more questions if I go down
that route :)
Thanks,
Patrick
