hi hippo and all,
I tried your binaries and it worked
http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
What I actually did is ... on my redhat-9 system I untared your pre compiled gcc and stuff, then through your already build file system's help I build my kernel and it worked perfectly fine.
I can now see file system in ram file system boot. But still facing some issues with nfs root ....
It doesn't look like any problem with buildroot or file system ....
I am getting following error while booting same kernel with nfs boot support enable
mm/vmscan.c 736 Kernel BUG!
mm/vmscan.c 738 Kernel BUG!

What I found is I have enabled bit swaping feature in my nios processor in fpga configuration. Next I will try disabling it and will update result on forum.
Thanks for all your help
