Booting from /dev/mtdblock/0

[Murtada Shah]

Hi,

I'm trying to boot from /dev/mtdblock/0 (root=/dev/mtdblock/0 in cmdline 
options)

When I boot from nfs, I can mount /dev/mtdblock/0 no problem from 
command line & unmount etc.

But if I pass it as the root= option, while booting it gets stuck.

With mtd debug level to 3 I see that it tries mtdblock_open twice... 
which it shouldnt..

"mtdblock_open
ok
mtdblock_open
mtdblock_release"

Then it hangs here for a long time.
What could be the cause?
