"Starting kernel ..." Lock Up

Am in development of a custom i.MX6 single-board computer and have built a u-boot image and a Linux kernel. Everything works fine until the Linux attempts to boot using a micro-SD card. This is when I get the 'Starting kernel ...' message and then nothing. Using an emulator I have determined that I am stuck in a loop, but don't know why I got there.

 

Environment variables:

bootdelay=3
baudrate=115200
ipaddr=192.168.1.103
serverip=192.168.1.101
netmask=255.255.255.0
rd_loadaddr=(0x1300000)
netdev=eth0
ethprime=FEC0
uboot=u-boot.bin
kernel=uImage

bootargs_base=setenv bootargs console=ttymxc0,115200
bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serveri
p}:${nfsroot},v3,tcp
bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; boot

0 0x2000; bootm
loadaddr=0x10800000

stderr=serial

Any debug suggestions would be appreciated.
