Kernel 3.13.0 won't boot with nouveau driver. Last message entered on display is an error about fb error, nouveau conflicts with EFI VGA, removing generic driver. All display updating ceases at that point. I was able to enter my password to unlock the LUKS partition, and according to the disk activity light it was taken and boot continued. I was not in a situation where I could try to connect to the system remotely, but I am fairly certain it booted with no video. This happens consistently with 3.13 - with 3.12.05-301, I get the same "font" on boot until that same fb conflict error, when it then switches to nouveau and displays the correct sized font for a 1920x1080 display - grub is not loading the video driver, which is another issue in and of itself.
Confirmed, reproducible. I performed a fresh clean install of F20 with KDE desktop after this bug was first reported. I attempted another update to rawhide with never installing the Nvidia drivers, so the system has had native nouveau driver on it since it was installed. Current rawhide version is xorg-x11-drv-nouveau-1.0.9-6.fc21.x86_64. Booting the 3.12.05 kernel allows the system to start up normally. The hardware involved is an ASUS G55VW laptop with a discrete Nvidia GTX 660m+, not Optimus enabled.

Double checked with many Kernels - the 3.13 branch will not boot with a graphical display with this bug. Kernels attempted: kernel-3.13.0-0.rc4.git1.1.fc21.x86_64 kernel-3.13.0-0.rc4.git5.1.fc21.x86_64 kernel-3.13.0-0.rc5.git0.1.fc21.x86_64 I am still booting with my last remaining Heisenbug kernel, 3.12.5-301.fc20.x86_64. Proposing as an F21 blocker, as F21 is unusable at the moment with it's native kernel and nouveau on GeForce GTX hardware.
Is this still a problem with 3.14?
Nightly build from 24 APR was able to boot into a GUI. The only live image I tried was the KDE one which had other major issues, but it did boot into the desktop.
Discussed at the 2014-07-09 Fedora 21 alpha blocker review meeting. This bug seems to have gone stale and it's not clear whether or not it's still valid for recent kernels. Please retest to see if this is still an issue.
per the feedback on 2014-04-28 the bug was resolved at that point, so I'm gonna go ahead and close this for now (of course, re-open if the segfault has recurred in current kernels, Dan.)
Bug was resolved long, long ago. Clearing the needinfo flag.
