Also happening on a Dell Precision 5520. Works fine without doc. Screen goes black and system locks up after login if docked. Cold boot is only option. Booting to 4.15.0-43 works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813796 Title: kernel bug null pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
