Hi Finn,
Nice! I'm going to have to put a real linux install on
this machine so I can test full size kernels. I just tried
compiling a 2.4 linux kernel and tried it on the floppy, and
again, it hung at the same point as the 2.6 kernel. I
wonder what's going on. . .
Thanks,
J Silverman

Hi Finn,
Yes, actually I have tried an older prebuilt
kernel
that Laurent made.
It was a 2.2.x series kernel, and it did at least
get
passed the point
that my 2.6.x kernel did before kernel panicking
later
on.
I got curious and dug out my PowerBook 190cs and tried
Debians's 2.6.25-2
kernel. I'm pretty sure that I downloaded it here,
http://people.debian.org/~smarenka/d-i/m68k/images/daily/kernels/vmlinuz-2.6.25-2-mac
There's also
http://packages.debian.org/sid/linux-image-2.6.26-1-mac
but I've not tried it yet. You can get the .config
from
the .deb there if you
need it.
There is no PMU ADB driver configured into Debian
kernels,
so the
PowerBook keyboard didn't work (which is not to
say
that the keyboard will
work if you do configure in the PMU ADB driver...)
There's a big warning from the IDE driver, though
it
still read the
partition map from the IDE disk. And there's the
bus
error from the
mac_scsi driver:

And it hangs there. This is an old bug. But I did get
macscsi to work --
it even booted to a login prompt -- by powering on the
SCSI
disk after the
kernel had started executing. So the bug is probably
nothing too serious.
The log from the most successful attempt follows.
I don't know if these results are at all
applicable to
the PB 520, but I'm
curious to know what it does. It would be helpful to
log
the serial port.
(A mac printer cable is fine if you are logging on
another
mac. I use
ZTerm and kernel arguments like those below.)
