Today's first GEM error came after several suspend/resume cycles while mobile when I attached the computer to a VGA display and enabled it via xrandr. The requested files attached. Hope this is useful.

This has Rawhide duplicate in bug 489907

FWIW, I have not seen the Xorg crash with F11, though I did see it randomly with F10. My current problem is limited to the kernel barf about gem tiling (but the system continues to operate afterwards).

I continue to see this or similar problem with kernel 2.6.29.6-213.fc11, now sometimes also when enabling the external display. Kernel taint below is due to VirtualBox drivers being loaded (but no virtual machines are running).

I'm getting the same error eache time I disable the external monitor.

I also got a complete freeze once, after enabling the second monitor.
My stack trace is (don't know why the kernel is tainted, I don't have any additional modules):

Oh, I see, I have misunderstood that comment (too many bugs at once). Do you want to say, that THIS bug has been fixed?

Yes, F11 still shows the kernel warning I've pasted here, but I have not been able to repeat them on F12 nightly live image. Xorg is stable on both, the warning seems to not have adverse effects on GM965/GL960.

http://www.smolts.org/client/show/pub_dc0ecb64-9a76-4bcc-becd-ffbb06da7a5a

I cannot reproduce it on F12.

Can this bug also be fixed in the F11 kernel?

I see this warning regularly when trying to log in on an T500 thinkpad on its
docking station with external display attached.  Sometimes I struggle like hell
to get the external display working again.  I normally end up with a random set
of symptoms, normally one of:

- monitor goes into power saving after logging in
  - normally requires laptop lid to be opened, wait, then shut, wait, hit some
    keys and hope it unblanks
  - blindly typing 'xrandr --output VGA1 --off' followed by 'xrandr --output
VGA1 --auto' (the second of which invariably seems to get corrupted despite
typing up-arrow, ^w, --auto)
- a mouse pointer which is fixed at one position on an otherwise black screen,
and it changes shape as I move the mouse
  - this seems to require an entire shutdown (as in power off) and reboot to
resolve.

I have many and regular submissions of this problem into kerneloops.

Thanks.

re #17 -- this kernel error never prevented me from using dual screen, either while docked or while plugging in a monitor/projector on the VGA port. It would simply produce the warning, but continue to function anyways. 

Then again, I DID also have a script in /etc/pm/sleep.d to toggle xrandr off/on during the syspend/resume cycle, because I wasn't happy with the Xorg defaults for the display layout.

I can confirm it's been eliminated with F12 kernel-2.6.31.5-127.fc12.x86_64. I no longer need the script, either, because F12 Xorg's defaults (VGA right-of LVDS) are exactly what I wanted to happen anyway. For rmk or anyone else who might benefit, this is the script I used:

$ cat /etc/pm/sleep.d/000xrandr 
#!/bin/bash

. /usr/lib64/pm-utils/pm-functions

DISPLAY=$(/etc/pm/find-console-display)
export DISPLAY

RETVAL=0
case "$1" in
	hibernate|suspend)
		# turn off external display before suspending
		xrandr --output LVDS1 --auto --output VGA1 --off
		RETVAL=$?
		;;
	*)
		xrandr --output LVDS1 --auto --output VGA1 --auto --right-of LVDS1
		;;
esac

exit $RETVAL

$ cat /etc/pm/find-console-display 
#!/usr/bin/python
import dbus, os
if not os.getenv("DISPLAY"):
  # Get the ConsoleKit manager
  bus = dbus.SystemBus()
  manager_obj = bus.get_object('org.freedesktop.ConsoleKit', '/org/freedesktop/ConsoleKit/Manager')
  manager = dbus.Interface(manager_obj, 'org.freedesktop.ConsoleKit.Manager')
  
  # For each of my sessions..
  for ssid in manager.GetSessions():
    obj = bus.get_object('org.freedesktop.ConsoleKit', ssid)
    session = dbus.Interface(obj, 'org.freedesktop.ConsoleKit.Session')
    # Get the X11 display name
    dpy = session.GetX11Display()
    if dpy:
      # If we have a display, set the environment variable
      os.putenv("DISPLAY", dpy)
      print dpy
      break
else:
  print os.getenv("DISPLAY")

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  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 '11'.

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 11'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 11 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

It's fixed in F12.

Reporter, do you agree with the comment 20, please?

Thank you

I have not seen this issue in F12 since comment 15 (end of last year)

I also cannot reproduce this bug on F12.
I had the issue on F11 but I cannot tell you when it's gone away..

Regards

Thank you for letting us know.
