[Bug 1575334] Re: Docking thinkpad laptop causes a complete system freeze
I've been dealing with this issue for two years now, happens about 30% of the time when I put it on the dock, after a restart it works fine. Since I don't have the time or knowledge to help identify this issue, at least I wanted to share the workaround I recently found: - Just never dock or undock when the laptop is suspended. Turn it on first, then dock/undock. Otherwise you're in trouble next time.

I am using Lenovo Yoga 260 with OneLink+ Dock and just started to have the same problem with Ubuntu freezing. I am using 18.04.1. Symptoms: (1) If I have it connected when I power up, it will hang and you can only hold down the power down button. (2) If I connect the Dock link after I power up BUT before I login, it will also hang (3) After I login, connect the Dock link, works fine.

I think I'm also affected by this issue (Thinkpad T450s). When changing the power management behavior for a closed lid (AC and Battery) to not suspend, I have no issues. I can then dock and undock. So this would be a work around. This issue is clearly related to the suspending behavior of a closed lid during docking. I even get a freeze when I would simply shutdown the system.

Hi Joseph, Sorry, but I haven't gotten around to trying the last kernel you posted. In the meantime, Xenial had a new kernel released: 4.4.0-25-generic. In this latest kernel, I can now dock without everything freezing - yay! However, I now can't undock without everything freezing - booo!
