Good time of day to all.
I`m trying to run FreeBSD 7.0 on PXA255 chip (board Palm Tungsten C).
Machine depended code partially write by me, and kernel started, but I
have big problem. Can`t resolve problem without experience in
internals of kernel.
So I put to kernel code many printf`s, and can see this picture:
KDB: debugger backends: ddb
KDB: current backend: ddb

__END__
last message about 'call uma_startup' in many boot try, dos not appear. So I think problem in page pointed by variable 'mapped'.
Kernel don`t panic, machine only freeze.
Maybe somebody know what`s is it?
Help please.
Thanks
