ext2fs or ramdisk problems......

[kd at flaga.is]

Hi,

Is it for shure that the ext2fs is endian independent?
fs created with the commands (issued in Debian 2.2. (potato) on an i386
machine) :

dd if=/dev/zero of=fs bs=1k count=4096
mke2fs -m0   fs 4096
mount fs /mnt/ramdisk/ -o loop
cd /mnt/ramdisk/
tar -xvf /tmp/fs.tar
cd /tmp
umount /mnt/ramdisk/
gzip -9 fs

results in the following......

etc.......
and then it hangs.

Or is this still the ramdisk driver teesing me?

Board is custom board with mpc823.
Kernel is the hard hat 2.2.13 with no nfs support, bootp or rarp support
built in.

Totally pussled!
