This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

Can you reproduce this easily? If so, can you give the v3.11.10 kernel a try:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.10-saucy/

[Joseph Salisbury (jsalisbury)]

Also, does the bug go away if you boot back into v3.11.0-14?

[Maarten Baert (maarten-baert)]

I had a crash with a stack trace that looks VERY similar, but this was on Arch Linux with kernel 3.12.6, with very different hardware. I am running firefox with the .mozilla folder in ecryptfs on an ext4 hard disk, and the crash happened while I was using firefox. Is that what you are doing as well?

The strange thing is, I have been doing the same for months on a different computer with no issues (also with kernel 3.11).

[penalvch (penalvch)]

Maarten Baert, thank you for your comment. So your hardware may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux

For more on this, please read the official Ubuntu documentation:
Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue
Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports
Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette

When opening up the new report, please feel free to subscribe me to it.

Thank you for your understanding.

[Maarten Baert (maarten-baert)]

@Christopher M. Penalver:
I can submit a new bug report with my hardware, but I am not able to reproduce this issue. So far I've only seen it happen once, and I don't know what triggers the bug. So the best I can do at the moment is give you a hardware report from Ubuntu with a trace from Arch Linux. Do you still want the report?

[penalvch (penalvch)]

Maarten Baert, a new hardware report from Ubuntu would be fine.
