problems on building root filesystem using scratchbox and meamo

["xuxian" <lsfdxuxian@gmail.com>]

Hi all,

I'm using scratchbox and meamo to build my root filesystem. I fallow the
steps shown in the HOWTO: Using flasher and the reference root filesystem.
The link is:
http://www.maemo.org/platform/docs/howtos/howto_use_flasher_rootfs.html
Finally, I got the jffs2 image of my root filesystem and download it to my
board OSK5912 successfully. But I meet the following error messages when
boot the kernel:
............................................................................

It seems the filesystem can work as NFS, but not stable. It can work once in
three times approximately, and in the other times it can't go further more
when the following messages shown on the console:
............................................................................
Looking up port of RPC 100003/2 on 192.168.0.11
Looking up port of RPC 100005/1 on 192.168.0.11
VFS: Mounted root (nfs filesystem).
Freeing init memory: 120K

My board is OSK5912 and the kernel is omap-linux-2.6.14.
I have had these problems for quite a while, but have never been able to
identify the cause. Dos anyone have experience in it? Any help will be
appreciated. 
Thank in advance.
Best regards.
