Here is a dmesg drm.debug=0xe log for debugging my problem (assuming it's related to this bug)

This dmesg is taken with 3.13 with drm.debug=0xe. The kernel framebuffer shows up on both monitors. After starting X only the secondary dvi head shows anything. I ran "xrandr --output HDMI-0 --set audio off --auto" and this brings the primary hdmi head back. After that I took the dmesg dump.

It's possible that my monitor is defect. It's been unreliable in the past.
