It sounds like the bug exists in the 4.2 final kernel, but it does not exists in Wily. That may indicated the bug existed in early versions of Wily, but was fixed in later versions.
Can you next test the latest upstream 4.2 stable kernel? It can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.8-ckt8-wily/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575334 Title: Docking thinkpad laptop causes a complete system freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
