... which is why my nightly autoboot tests regularly fail if I undock
and redock the laptop, and forget to manually rebind the serial port...
because the vendor supplied ACPI tables seem to be broken, and there's
zero interest from the vendor to fix such an issue.

They're certainly not going to fix it based on one report from an
end user using an obscure operating system which seems not to have
any support in mainline for such oeprations in any case.
