Rootfs in eMMC: Kernel panic ...Attempted to kill init!

I am trying to boot linux on SMP system with root file system(ext2) on eMMC.
The eMMC is partitioned in 3 parts and I am trying to use 2nd
partition of 128M to keep
The command line used is:
Kernel command line: cachepolicy=writealloc noinitrd
root=/dev/mmcblk0p2 rootfstype=ext2 rootdelay=1 init=/bin/sh rw
After mounting the rootfs in eMMC, it panics.
Panic log as below. When I traced, I observed it fails while its
I have tried with different init process,i.e. init=/linuxrc,
Even I tried initramfs and the switch_root/pivot_root to rootfs on
In all the cases, I got the same panic.
Can anybody help me in understanding the exact reason for this panic?
DRIVER MMC: probe
Waiting 1sec before mounting root device...
mmc0: new MMC card at address 0001
mmcblk0: mmc0:0001 M8G4DD 8028160KiB
mmcblk0: p1 p2 p3
VFS: Mounted root (ext2 filesystem).
Freeing init memory: 108K
