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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1459052 Title: CPU lockup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1459052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
