@richard: what can we do ? i am no expert in this either. But my guess is supporting this thread: https://bugzilla.kernel.org/show_bug.cgi?id=109051 is the right thing to do, cause it is the bugreport at the right place, meaning the kernel bug list. This thread here is a ubuntu bug report, and actually ubuntu is not the problem.
it is a very difficult problem, there is no reproduction scenario, no trace-dumps or anything that could help debugging this. for me it is not too tragic as i can operate everything i need with kernel v4.1.12 btw in that kernel bug thread mentioned above the latest reported kernel to work is 4.1.15 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509723 Title: [Acer Aspire ES1-311] Ubuntu freezes occasionally To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
