Any chance you could bisect to see what the fix was?
I got my hands on a spare disk and did the bisect. Strangely enough this turned up (!?)
["first bad commit" meaning good, since I had to invert bisect bad/good]
ad41550666f89b5af9335fcde9e98b61190daf99 is the first bad commit commit ad41550666f89b5af9335fcde9e98b61190daf99 Author: Alex Deucher alexander.deucher@amd.com Date: Thu Sep 26 13:11:18 2013 -0400

Just to make sure, I double-checked...
uname -r && dmesg |grep 'VM fault' 3.12.0-rc3-ARCH-00404-gad41550
uname -r && dmesg |grep 'VM fault' 3.12.0-rc3-ARCH-00403-g10ebc0b [ 18.716461] VM fault (0x00, vmid 0) at page 0, read from unknown (0) [ 18.716466] VM fault (0x00, vmid 0) at page 0, read from unknown (0) [ 18.716470] VM fault (0x00, vmid 0) at page 0, read from unknown (0) ...
GDM successfully starts with the 1st and fails with the 2nd.
What does this even mean, how can disabling HDMI audio break things? :)
