Comment 12 for bug 1581761

Help. I can't help myself. I've read many similar issues but without luck. I did memtest, autoclean, I even enabled only single core just to be sure it's not some way of concurrency issue.

Right now I've installed 3.13.0-83 kernel as I believe it was the one I've used without any problems before all this troubles.

Below is my apt history which can be treated like suspect as it was last installs before problem appeared. However I didn't find any critical package here (like lvm, luks) but maybe one of you will find something strange:
