What is your bootargs ?  We also encountered this issue long time ago. 
The following bootargs line would cause this problem:
setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 
rootwait rootfstype=ext3 ro'

Try to change "console=tty0 console=ttyO2,115200n8" to 
"console=ttyO2,115200n8 console=tty0" .
Please refer the bug 1823 
(https://bugzilla.yoctoproject.org/show_bug.cgi?id=1823).


Thanks,
Yi
