gdm fails to start with external monitor

Created attachment 604053 [details]
Xorg.0.log for a failed attempt
Description of problem:
If I have my external monitor attached to DVI I can just see the background image on the laptop and the external monitor stays blank, no gdm login or anything. Without the external monitor everything is normal and I can login, then connect the external monitor and it remembers my setting to extend the desktop.
Version-Release number of selected component (if applicable):
Linux disi-bigtop 3.5.1-1.fc17.x86_64 #1 SMP Thu Aug 9 17:50:43 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
1. boot with an external monitor attached to DVI
Here is another scenario:
1. boot with the external monitor connected
2. just the background image and mouse pointer, where gdm should be
3. disconnect the monitor and restart Xorg (ctrl+alt+bksp)
4. gdm comes up and I can login
5. wait for Gnome to start
6. connect the external monitor and I get a kernel oops (tested twice)
cannot login with external monior
gdm to prompt for username/password

I thought I report this, since it first worked after fresh install of Fedora 17 and then with updates it stopped working. The problem is there for more than a week now and even after a couple of updates, including kernel upgrade, the problem still persists...
I found out, if I suspend and then disconnect the monitor, then login, wait for Gnome to load, connect the monitor, works as well
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
