FreeBSD on PXA255 board

[Alexandr Rybalko]

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:

__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
