Hi Mika, Bother you again because you are the only TBT expert that I know of ;) We are enabling a new CFL desktop with TBT card. The TBT card in question doesn’t get enumerated at cold boot, so the card isn’t listed under `lspci`. Anything that does a PCI scan (# echo 1 > /sys/bus/pci/rescan, S3, warmboot) can make the card gets detected correctly. The same TBT card doesn’t have the issue on a KBL desktop, so I not sure if it’s a driver issue though. Also, is there a more appropriate mailing list for TBT discussion? Kai-Heng
