the kernel you use - vanilla+ppc-patch - is based on linuxppc-2.4,

    I just tried. The result is the same. Using the original

it hangs in mapin_ram().
    If I use minimal config, it hangs in __sti().

2.4 kernel on that? If no, could someone remember what is the last known
working toolchain and kernel on Walnut?

I noticed this about a week ago.  It is some kind of merge problem
between linux-2.4 and linuxppc-2.4.  linux-2.4 boot fine on walnut
for me.  I didn't have time to investigate but might take a look at
it again soon.

    Really? That's so great! Do you have any idea about this? Maybe I can
try to investigate as well. Also, do you remember what is the version just
before this merge problem occurs? Thanks.

Well, maybe I should have cleaned my tree from a 440 build, I had
an old CONFIG_440 hanging around causing the kernel to not be
happy.  At any rate, I verified that current linuxppc-2.4 boots
on walnut from stock openbios.
