Hi Hui Wang and all others,
thank you for notifying me and for giving it a new run for the
kernel! ;-)

After the commit 0ec4e55e9f57 ("ACPI: resources: Add checks for ACPI
IRQ override") is reverted, the keyboard of those Medion laptops can't
work again.
To fix the keyboard issue, here adding an override check by DMI info,
this will not affect other machines and this design refers to
the prt_quirks[] in the drivers/acpi/pci_irq.c.
If we meet similar issues on other platforms, we could expand the
table of skip_override_table[] or medion_laptop[].

enables additions, allowing the kernel to work-around other buggy
BIOSs / hardware properly in future.
Maybe https://bugzilla.kernel.org/show_bug.cgi?id=213353 "IRQs
for onboard UARTs are not level-triggered with IRQNoFlags even if
the parent section has the defaults in PRS" is another candidate
to add to the table (but I haven't digged deeply enough into it
to be sure).
Many thanks to all helpful people involved,
best regards,
Manuel
