Hi Cole, It seems not a new issue, see these: https://lkml.org/lkml/2012/12/13/589 http://help.lockergnome.com/linux/Linux-Support-Thunderbolt-Apple-Monitor--ftopict553657.html Maybe Thunderbolt hotplug is not well supported now. If this issue does disturb you, you can try Kirill's patch , maybe it can help you.:) thanks, Gu > -- > To unsubscribe from this list: send the line "unsubscribe linux-pci" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
