<pre>Andrew, I think you need to figure out your ACPI problem first. Just a shot in
the dark, maybe try pci=noacpi.
David, the dmesgs you've reported have kernel v3.2 and no drm.debug=14 module
parameter.
In any case, v3.16 kernel should more or less support Broadwell; I don't know
about the userspace versions.
I'm inclined to close this as INVALID.</pre>
