I have two USB3 Docks (Asus HZ-1 at home, Toshiba Dynadock at office). Every day in the evening I put my laptop (Razer Blade Pro) into sleep with Asus USB dock plugged in. Next day in the morning I unplug the dock (laptop still sleeps) and move to the office where I plug in another USB3 dock (Toshiba). Then I resume the laptop. In the afternoon I do the same while moving home. Until kernel got upgraded to 3.15 I had no problems, since 3.15 my laptop freezes completely with 50% probability while resuming from sleep. Laptop also freezes sometimes when I simply plug the dock into the running system.
