Bad page map / bad pte

[Ray Cole]

I have received very similar bugs on 3.13.0-53, 3.13-0.52, 3.13.0-51 and 3.13.0-49. I will be falling back to 3.13.0-45, which is the last kernel where I believe I didn't have this problem.

Ray Cole, 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/Kernel/MainlineBuilds ? 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-X.Y-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-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

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.

I have installed 4.1.0-040100rc7-generic and will see if this problem happens. It usually takes several days for the problem to appear.

I had fallen back to 3.13.0-45 and it ran over a week without the problem. 3.13.0-49 produced the problem after only a few days. So something between -45 and -49 caused the issue it seems.

[Ray Cole (the-other-ray-cole)]

So far 4.1.0-040100rc7-generic has been running without a problem. Because this problem is intermittent I want to give it another week of running before marking it as fixed upstream.

[Ray Cole (the-other-ray-cole)]

I am convinced the problem is resolved upstream as it has run an entire week without causing a problem. Added tags indicating it is fixed upstream. I am also installing 3.13.0-55 to see if this also resolves it.

[penalvch (penalvch)]

Ray Cole, if the latest 3.13 kernel does not address the issue, to see if this already fix in Ubuntu, could you please test this in http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Ray Cole (the-other-ray-cole)]

I would be willing to run the kernel from it if I can obtain it somewhere. It takes about a day to reproduce the problem. The first symptom are things randomly crashing (google-chrome, for example) and then not too long after I see messages about pte problems.

3.13.0-46 and below run fine. 3.13.0-49 and above crash. I have not tried 3.13.0-48 but intend to do so in order to nail down which one introduced the problem. It was either 3.13.0-48 or 3.13.0-49 that introduced it (or -47, but that doesn't appear to be available so I assume it was known to be bad).
