While there were some initial problems with Thunderbolt support on Linux, most of the early problems with the new technology have been worked out with recent kernel updates. Unfortunately, some problems remain with this high-speed I/O interface.

There were some Thunderbolt Display problems, while now the display and other functionality of high-end Thunderbolt displays like those from Apple are working aside from some cases still of high CPU utilization. There's also been other random bugs with Thunderbolt Linux support for different devices.
