Comment # 6 on bug 1218393 from robert spitzenpfeil

It's still there.

I've had a couple of days "peace", but now it's back. It may very well be a
hardware defect.

I'm getting a lot of these log entries.

Moving the display hinge or shaking the laptop etc. doesn't change anything,
nor does it trigger the issue.
