It doesn't appear that your machine is hanging, but rather bouncing
on HDMI connect/disconnect. Jose reported this a while back:
Can you try applying this patch into sources/meta-fsl-arm-extra?
~/yocto/sources/meta-fsl-arm-extra$ patch -p1 < 0001-*.patch
We've seen some issues with particular monitors (especially DVI) where
the DVI/HDMI detection pins seem to "bounce" when X starts up.
This kernel version includes a patch which bypasses the HDMI/DVI
