I'm not sure how the bridge initialization is supposed to work with TB3 security. But, I would guess that the dock needs to be authorized first before the PCIE bridges can be initialized.
Since the BIOS is not handling the TB3 authorization, it might not be able to access the bridges. So the task of bringing them up would fall to the OS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1696325 Title: USB, display and ethernet ports in HP Thunderbolt dock don't work Status in linux package in Ubuntu: Confirmed Bug description: I have laptop HP ZBook G3 Studio with Thunderbolt dock P5Q58AA.
