It doesn't appear that your machine is hanging, but rather bouncing
on HDMI connect/disconnect. Jose reported this a while back:

	https://lists.yoctoproject.org/pipermail/meta-freescale/2013-October/005113.html

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
disconnect code:
	https://github.com/boundarydevices/linux-imx6/commit/d9cd79d11ff9f7a7f89cbc94b68757b67cdfe5fc


Please advise,


Eric
