Same in a T460p, using the Ultra Dock station connected via HDMI to an external monitor (that actually routes through DP3-1). I see these errors multiple times, and I also experience some hangs where I see visual corruptions in monitor. Not sure this can be related, but indeed it has something to do with intel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523088 Title: WARN_ON(!wm_changed) warning and stacktrace in kernel log To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1523088/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
