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.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.11 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.

[Conrad Yang (cpyang)]

My system is running on ZFS, which is not compatible with v3.11-rc5-saucy now. I'll test it once the ZFS compatibility issue got solved. This issue exists with v3.10.0-997 from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2013-07-13-saucy. Disable internal screen might have better chance that displayport will work, but not always.

And has been seen on ThinkPad X220 for a few times, but it's mostly work with dual screen (internal+displayport) on ThinkPad X220.

[Conrad Yang (cpyang)]

Still got the trace message in dmesg with v3.11-rc5-saucy, while dual screen works on reboot.
Switching screen layout might generate more trace messages, but screen display is fine.

I get this crash every time during boot. Got a Xeon E3-1245 V2 (HD Graphics P4000) connected to a Dell U2713HM via DisplayPort. Seems related to the bug report.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

Conrad Yang, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this in a live environment of the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please capture the call trace.
