Hi, guys. Sorry for entering your talk I have a Sony Vaio SVZ1311Z9RXI and just tested your patched against 3.10-rc7 and they work like a charm scenarios tested: - boot with dock - boot without dock, hotplug dock - dock / undock / redock All devices tested to be working in all 3 cases: - video card - ethernet controller - blue ray drive - USB controller Thank you a lot!
