1. configure haswell platform with 2 monitors
2. start X or lightdm will crash Ubuntu kernel, see the crash errors attached.

reported in upstream about linear tiling mode support
https://bugs.freedesktop.org/show_bug.cgi?id=61152

[Brad Figg (brad-figg)]

This change was made by a bot.

[James M. Leddy (jm-leddy)]

Patch merged to drm-intel-fixes as:

commit bc752862170c135d6c09fb22d79eeb451023568e
Author: Chris Wilson <email address hidden>
Date: Thu Feb 21 20:04:31 2013 +0000

    drm/i915: Handle untiled planes when computing their offsets

[Jammy Zhou (jammy-zhou)]

James, is the fix available in updates of Ubuntu 12.04.2 for verification now?

[James M. Leddy (jm-leddy)]

Jammy, it is not yet. I'll build a test kernel to send you to verify, and then I'll submit to kernel-list. After that we will have a test kernel for verification.

[Jammy Zhou (jammy-zhou)]

Perfect. Thanks James.

[James M. Leddy (jm-leddy)]

Apparently, this bug and freedesktop-bugs #61152 are not related. Going back to the original userspace backtrace, can we get a core file from when this occurs? If you're using apport, this crash should be in /var/crash.

[kevin.liu (kevin-liu)]

I didn't find the crash report under /var/crash, but re-produced the issue and save the crashed kernel log as the attachment.
Thanks

[kevin.liu (kevin-liu)]

additional notes:
I didn't duplicate the issue with an external 1920x1080 monitor.

I watch the issue with an external 1280x1024 monitor.

assuming this has fixed itself since
