Secure Boot Process unable to complete boot: "Waiting for root device"

Hi, I am trying to implement secure boot in my imx6sxsabresd board. I had successfully signed the u-boot and have managed to boot it without getting any HAB_EVENTS. Furthermore, I have also blown the SEC_CONFIG[1] fuse bit using the command fuse prog 0 6 0x2. When I boot my system from my SD card, i encounter 2 problems: 

1) The reset SW3 which is used to reboot the system is not very responsive: I need to press it several times (3-4 times) before it reboots. This was not the case before I blew the SEC_CONFIG[1] fuse bit. 


2) The boot process continues until the line "Waiting for root device /dev/mmcblk0p2" where it stops indefinitely. I am new to secure boot and am still learning the ropes. Therefore, I am not sure if i would have to sign the kernel and the rootfs in order to see a successful secure boot. 


Attached file has the output of the boot process that is giving me problems. Any help is greatly appreciated.
