Re: kernel stuck when decompress initrd

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?

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.
