ramdisk mount problem

[Prakash kanthi]

Hi Folks,

I am trying to use 2MB ramdisk image from denx as my
linux filesystem. Linux kernel fails to mount the
'ext2' type file system from initrd. I pin pointed the
problem.

Looks like the problem is in 'do_mounts.c ->
mount_block_root' function where a call is made to
sys_mount as follows:

'int err = sys_mount(name, "/root", p, flags,
root_mount_data);'

In my case name="/dev/root", p="ext2", flags=32768 and
root_mount_data=<NULL>.

The result of this call is EINVAL, i.e. invalid
argument. Can anyone help me out find which one of the
arguements could be invalid? If 'root_mount_data' is
the culprit, why is it null? I see that it's value is
set in one of the __setup functions. When are these
functions supposed be executed? I know that all
__initcalls are executed from dO_initcalls.

This failure causes Kernel Panic, complaing about
"Unable to mount root fs at 01:00".


Thanks,
Prakash
