init hangs

[Saravanan Chanemouganandam]

Hello,

I forget to add the steps that I have done in configuring the Buildroot.  In 
the buildroot menuconfig, I configured Kernel option as "none" and kernel 
header version option as "2.6 latest snapshots" for my existing linux 2.6.16 
and then compiled using make as

../buildroot# make LINUX_HEADERS_VERSION=2.6.16 DEFAULT_KERNEL_HEADERS=2.6.12
