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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1459052 Title: CPU lockup Status in linux package in Ubuntu: Incomplete Bug description: CPU lockup experienced.
