kernel stuck when decompress initrd

[Kim, Jin Young]

Hello,

I'm trying to run LINUX 2.3.99 image on SBC8260 boards.

The kernel stopped after showing following messages on console.
I'm really novice to LINUX, so only debugging way is printk.
I found the kernel stopped in flush_window() in drivers/block/rd.c.
It is in the middle of gunzip() procedure.
Any idea?  Something wrong in the sequence?
I'm using vWARE boot rom from EST to boot LINUX.
I tried to boot LINUX from FLASH SIMM on the board(it is 0xe0100000),
but worse than from RAM. it only shows first boot loader messages.

Regards,
Jin
