Hi.
I have a problem about ramdisk.
Kernel version: 2.6.3 and 2.6.4
root@fen:~# dd if=/dev/zero of=/dev/ram0 bs=1024 count=2048
2048+0 records in
2048+0 records out
root@fen:~# mke2fs /dev/ram0
mke2fs 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
Filesystem label=
....
root@fen:~# mount /dev/ram0 /mnt
root@fen:~# ls -al /mnt

drwxr-xr-x 3 root root 1024 Mar 29 20:28 ./

root@fen:~# umount /mnt
root@fen:~# mount /dev/ram0 /mnt

My test file does not appear on /mnt.
This was working with 2.4 kernels
i think the problem is related with 2.6 kernels
What is the problem?

Verify that /dev/ram0 is not still mounted on /initrd.
I noticed that the stuff that uses initrd and pivot-root
for booting, works 'strangely' compared to the past. You
may find that /initrd remained mounted when you initialized
its virtual device, confusing the issue.
Cheers,

It's a 2.6 bug which I haven't fixed yet.
