kernel stuck when decompress initrd

[yama at isd.mci.mei.co.jp]

Hello,

But,this is not the answer on this problem( kernel stuck when decompress
initrd)
I also worry about the same proglem.
I'm trying to run LINUX 2.2.13 image on our custom board.
I also found the kernel stopped in flush_window() in drivers/block/rd.c after
showing following messages on console.

Does anybody advise on this problem?

Regards,
