Hello Wolfgang,
Thanks for your reply. I have checked that my total file size is only
384KB, and the ramdisk I created is 4096KB, and my Kernel's ram size
CONFIG_BLK_DEV_RAM_SIZE is set to 4096.
Here are the steps I used to create ramdisk:
dd if=/dev/zero of=/dev/ram bs=1k count=4096
mke2fs -vm0 /dev/ram 4096
mount /dev/ram ramdisk/
cd ramdisk/
cp -r /home/devel/root/* .
mkdir dev etc tmp var proc mnt home root
cd dev/
mknod console c 5 1
mknod ttyS0 c 4 64
mknod tty c 5 0
mknod ram0 b 1 0
mknod ram1 b 1 1
mknod mem c 1 1
mknod kmem c 1 2
mknod null c 1 3
mknod zero c 1 5
mknod fb0 c 29 0
ln -s fb0 fb
ln -s ram1 ram
ln -s ram0 ramdisk
ln -s ../proc/kcore kcore
ln -s ../proc/self/fd/0 stdin
ln -s ../proc/self/fd/1 stdout
ln -s ../proc/self/fd/2 stderr
cd ..
umount ramdisk
dd if=/dev/ram bs=1k count=4096 | gzip -vf >
/home/devel/linux/arc/mips/ramdisk/ramdisk.gz
Any other suggestion?
p/s: I have got lots of junk mails sent from this mailing lists,
probably triggered by my email. Could the administrator do something?

I built Linux kernel (V2.4) as follows:
- Created EXT2 ramdisk.gz as documented in Documentation/ramdisk.txt
- The ramdisk contains the content of buildroot/build_mipsel/root/, which contains bin, etc, lib, linuxrc, sbin (sh.. etc), usr. I also created under /dev console null, tty*....
- Copied ramdisk.gz to /linux/arc/mips/ramdisk/
...
Tracing down the codes, I noticed I got EXT2-fs error.
Your ramdisk is probably much bigger than the kernel's default of 4 MB.
