I found a couple existing bugs in the freedesktop.org tracker that might be related, all marked as fixed in recent nightlies:
https://bugs.freedesktop.org/show_bug.cgi?id=96714 https://bugs.freedesktop.org/show_bug.cgi?id=95498 https://bugs.freedesktop.org/show_bug.cgi?id=94822 https://bugs.freedesktop.org/show_bug.cgi?id=89055 There's also some indications this may be related to 4k monitors as well; my original crash with the ThinkPad Dock and Ubuntu's 4.4.0 kernel was a FullHD monitor, later tests with 4.6 and 4.7 were all with a 4k DP 1.2 monitor. I'll have to test again with the dock and a non-4k monitor once I get my hands on it. ** Bug watch added: freedesktop.org Bugzilla #96714 https://bugs.freedesktop.org/show_bug.cgi?id=96714 ** Bug watch added: freedesktop.org Bugzilla #95498 https://bugs.freedesktop.org/show_bug.cgi?id=95498 ** Bug watch added: freedesktop.org Bugzilla #94822 https://bugs.freedesktop.org/show_bug.cgi?id=94822 ** Bug watch added: freedesktop.org Bugzilla #89055 https://bugs.freedesktop.org/show_bug.cgi?id=89055 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1597267 Title: ThinkPad X260 connecting external DisplayPort hangs system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1597267/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
