Description of problem: When attempting a normal boot with any version 3.8 kernel, when modesetting is attempted, the monitor loses the signal and never gets it back Version-Release number of selected component (if applicable): kernel-3.8 all versions up through kernel-3.8.0-0.rc7.git2.1.fc19 How reproducible: 100% of the time Steps to Reproduce: 1. Install a version 3.8 kernel 2. Reboot Actual results: Initial text displays properly Signal to monitor goes away never to return when kernel modesetting kicks in Expected results: Computer will boot normally as it does with all F18 kernels Additional info: Onboard Nvidia 9100 graphics Monitor has known bad EDID - works fine earlier kernels and custom xorg.conf Current working configuration: kernel-3.7.7-201.fc18.x86_64 xorg-x11-drv-nouveau-1.0.6-3.fc19.x86_64 xorg-x11-server-Xorg-1.13.99.901-4.20130109.fc19.x86_64
*** Bug 910946 has been marked as a duplicate of this bug. ***
Sorry about the duplicate - had no indication this was sent. Same problem occurs on my wife's system using onboard Nvidia GeForce 6150 LE graphics.
Tried a new kernel on an otherwise-working F18 system: kernel-3.9.0-0.rc0.git5.1.fc19.i686 xorg-x11-server-Xorg-1.13.2-2.fc18.i686 xorg-x11-drv-nouveau-1.0.6-1.fc18.i686 Same problem, suggesting that its something the kernel is doing that it didn't previously do that is causing the problem.
Looks like a kernel bug, not an Xorg bug. Took the following two blocks from /var/log/messages. Note 3rd line of block using 3.9 kernel. Google results suggest this error crops up from time to time with various kernels. 3.9 kernel (fails): Feb 26 08:25:42 Pyrope kernel: [ 7.153565] nouveau 0000:02:00.0: VGA-1: EDID block 0 invalid.

Created attachment 703567 [details] Smolt profile from working (kernel-3.7) boot
kernel-3.8.3-201.fc18.x86_64 still exhibits this problem
Have moved beyond kernel 3.8 (and will be moving off of F18 completely, as F20 alpha works well enough), so closing this bug
