All the lspci outputs are identical. The drives did not work if the system was booted while undocked, or if the base's undock button was used.
If I had to hazard a guess, I'd say that docking the laptop should be triggering an ACPI:docking event and it's not. There might also be a problem of whether the drives are detected on initial boot.
