** Attachment added: "Boltctl output" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1950780/+attachment/5540412/+files/boltctl.txt -- 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/1950780 Title: Thunderbolt dock usb ports not working Status in linux package in Ubuntu: New Bug description: I have a Lenovo Thunderbolt 3 Gen 2 dock and wanted to use this with Ubuntu 21.10. When booting an unmodified version the usb ports do not work. After an inspection with journalctl I find the error message "No bus number available for hot-added bridge" and a google search led me to this workaround: Add pci=realloc,assign-busses,hpbussize=0x33. This line as a boot parameter makes the dock work as intended. I believe this should be fixed so that people using the live image can see that their hardware works as intended before installing.
