CPU lockup

[Ray Cole]

CPU lockup experienced. Appears to be a bad PTE? Left google-chrome running for hours, untouched. Went to use it again and chrome stopped responding. dmesg showed a CPU stuck. Farther up it showed a bad PTE.
Machine passes memtest86.

Ray Cole, could you please test for this with Ubuntu (not Mint) via http://cdimage.ubuntu.com/daily-live/current/ ?

If reproducible, please execute the following in your installed Ubuntu environment:

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.
