Thanks for the feedback. Since it's fixed in mainline, we can perform a "Reverse" bisect to identify the commit that fixes the bug.
We first need to know that last bad kernel version and first good kernel version. Can you test the following kernels: v4.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9/ v4.10: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/ v4.11-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11-rc1/ You don't have to test every kernel, just up until the first kernel that does not have this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1677575 Title: Thunderbolt hotplug causes system hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1677575/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
