Public bug reported:
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.
