Additional datapoint since I just ran into this bug but haven't yet managed to upgrade the firmware.
I am running Debian Testing right now on a new x240 with the ultradock. I was testing this and, just as gdm was about to start up, I docked the system. Kernel is now saying "task kworker/1:3:1450 blocked for more than 120 seconds" and "task Xorg:1647 blocked for more than 120 seconds" followed by "Not tainted 3.12-1-amd64 #1" I'll apply the firmware updates, but it I thought this might help someone who was searching for an answer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
