[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1182386

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Thomas Hood (jdthood)]

I can't run `apport-collect 1182386` because I am behind a firewall. I can't run apport-cli because of https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1023964.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Similar messages have been reported against Linux 3.8.1 and 3.8.2 here:

* https://bugzilla.redhat.com/show_bug.cgi?id=917392
* https://bugzilla.redhat.com/show_bug.cgi?id=919120
* https://bugzilla.redhat.com/show_bug.cgi?id=921598
* https://bugzilla.redhat.com/show_bug.cgi?id=929220

The third of these includes the comment "Always occurs when connecting or disconnecting my DisplayPort monitor".

I also have a DisplayPort-connected monitor, so it won't surprise me if that is a common factor. I disconnected the monitor and got the following (different) warnings in dmesg. Reconnecting the monitor did not result in any new warnings.

I'm having some minor random glitches with graphics, so I searched syslog for intel and came across the same. I'm on Raring but running kernel 3.10.0-031000rc6-generic.

I'm having this issue on both precise and raring on ThinkPad X201.
This issue only appears when external display attached to DisplayPort.

The behavior is consistent with stock/mainline kernel with stock or intel linuxgraphics drivers (3.8.0-26-generic, 3.8.0-27-generic, 3.8.0-27-generic with intel linux-graphics 2013Q2, 3.10.0-997-generic,3.10.0-997-generic with intel linux-graphics 2013Q2).

External display works perfectly on VGA port.

I'm having this (or a similar issue) issue with the internal display (and the intel video card) of an hybrid video card vaio laptop, using bumblebee.
