kernel BUG at /build/buildd/linux-3.13.0/mm/slub.c:3365!

[Phil Ayres]

Periodically (every few days) I'm hitting this kernel bug, which causes the session to close and drops me back to the login screen. If I attempt to login it does some stuff (usual screen flashes) then drops me back to the login.

It seems to be when I'm doing something related to an item on the top Unity panel. I thought for a while it was when I was trying to activate Skype from the icon it places in the panel (so I assumed Skype was at fault). But I've just had it happen too when attempting to pick Sound Settings from the audio panel icon.

I'll be happy to provide other information if I can.

Phil Ayres, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.
