Trouble while running linux on custom PPC405GP board

Hello All !
I'm new in embedded linux and trying to run linux (2.4.22) on PowerPC
(405GP). It boots nice, but when it tries to execute /sbin/init it
hangs. Last console messages
are:
.......
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 56k init 4k prep

I've tried to replace /sbin/init by my own executable - it's
definitely have
not been executed.
I've traced it to the "last point" in kernel-mode (instruction "rfi"
in file
arch/ppc/kernel/entry.S:389). Everything OK before this point. But
after this step kernel just hangs.
After this sysrq-t prints that process init are running at c0007190
(this is
in the arch_kernel_thread).
sysrq-p doesn't print any registers, just the line "SysRq : Show
Regs".

Could someone give me any tips how to handle this trouble?
