The CalDigit TS3 dock is pretty solid for me on Linux, though sometimes it doesn't power on the DisplayPorts and the dock itself needs to be reset. I have a smart plug to do that.
However - given the high performance and deep system integration (PCI,USB,video) that Thunderbolt provides it's fairly extraordinary that hotplug works at all!
