Thank you Machael this will help when I switch back to that kernel version,
because now I'm using the kernel 2.4.3-pre4 that I caught from
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/. And it compiles ok with modules
support.

My problem now, is when I try to load the modules.

When I run:

sh-2.03# modprobe mtdchar

It fails with this error:

can't locate module mtdchar

And the modules are all there instaled in
$TARGET/lib/modules/2.4.3-pre4/...

sh-2.03# ls -lR /lib/modules/2.4.3-pre4/

The modules.dep file is empty, is that right ?


Here is the boot message:

Take a look at the line just before INIT, what is this module char-major-4
about ? Is that the problem ?

Any help would be very appreciated.
