Hi Clark,
Thanks for the attention. I just looked at error message before the trace I posted.

setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: No such file or directory

Only if I set CONFIG_SYSFS_DEPRECATED_V2=y, I could successfully boot
which I have tested with this kernel in same system.

Is it not set by default from 2.6.31 onwards ?

Thanks,
Gowri
