hello:
i got a problem like this:
loaded at: 00100000 002C5AD0
board data at: 001001C4 001001E0
relocated to: 00200100 0020011C

initrd at: 0013A400 003116E2
avail ram: 00312000 01000000
Linux/PPC load:
Uncompressing Linux...done.
Now booting the kernel

length error! orig_len=0x400000,bytes_out=0x4000d5
i added some prink() for debug ... ;)
my ramdisk.image.gz is broken?
but i can mount(-o loop) it in my host(i386-linux) after gunziped.
and how to creat a correct ramdisk image?
using following step?
mkfs -t ext2 /dev/loop0
mount /dev/loop0 /mnt/rd
mkdir /mnt/rd/bin /dev ...
cp bash etc. to /mnt/rd/bin ...
mknod ....
dd if=/dev/loop0 of=./ramdisk.image
gzip -9 ramdisk.image
what can i do?
thanks for any help.

Hi,
Your cmd_line is possibly using the memory zone where the compressed
ramdisk is stored.
In arch/ppc/mbxboot/misc.c, cmd_line = 0x200000 if CONFIG_MBX is not
defined.
