Created attachment 91609 [details] [review] testing patch
Does the attached patch help? If so, try and narrow down which changes fix the issue.
I have added this patch to the Fedora kernel 3.13.0-0.rc7.git2.1.fc21.x86_64 and the results are the same, sometimes it halts while the kernel is booting, and other times I can even login in KDE, but suddenly the screen is corrupted and goes black.
I attach some logs of when I was able to boot and take them.
