--- Comment #29 from Jani Nikula <jani.nikula at intel.com> ---
This bug seems to have been neglected a bit, apologies. I'm afraid we don't
have much clues on it either; it smells like a bios and driver cooperation
issue. I can only ask you to try a recent kernel.

I'd appreciate a dmesg with drm.debug=0xe from early boot, running a recent
kernel (preferrably v3.17-rc or drm-intel-nightly) with:
1) bios w/a off (since IIUC there's no problem with another BIOS setting)
2) boot with vga disconnected (since IIUC there's no problem booting it
connected)
3) connect vga
4) run xrandr --verbose (and attach the output too).
