@Kai Heng: It should not be machine/chipset specific, but may have some BIOS component to this due to BIOS sends the hotplug event. If the hotplug event comes too soon (before enumeration is done) you should see this behavior.
It's specific to PCIe tunnels of TBT devices. You won't for example see it if you connect a non-TBT type-C device to the the type-C port of the TB16 or a display to one of the display ports. The USB hub and USB ports are however behind the PCIe tunnels though and should hit this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697395 Title: Thunderbolt devices don't work if connected during boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1697395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
