Bug description:
[Impact]
Keyboard and touchpad doesn't work on some recent systems, and also
s2idle is broken.
[Fix]
Two upstream commits.
128b0c9781c9f26 x86/i8259: Skip probing when ACPI/MADT advertises PCAT
compatibility
3bde7ec13c97144 platform/x86: Add s2idle quirk for more Lenovo laptops
[Test case]
boot a fixed kernel and test that input and s2idle works.
[Where problems could occur]
A buggy bios could maybe advertise a system being PCAT compatible when
it's not, though in such a case it might have been already caught
before.

Hello.
Ubuntu 22.04.3 with (later upgraded to kernel 6.2.0-32-generic) was
installed in rewly purchased LENOVO V15 GEN4 AMN (AMD Ryzen 5 7520u)
laptop and it was noticed that keyboard, touchpad and microphone are
not working. The keyboard and touchpad work fine in BIOS setup and
till GRUB (command line). It was found that when external devices such
as keyboard, mouse and microphone are connected through USB and 3.5
jack, respectively, these work just fine. To confirm these are not
hardware problems, Microsoft Windows 11 (Home) was installed in
another disk partition and observed all these working alright. Hence a
bug is being reported to draw attention of the concerned team and I
request them to refer this issue and do the needful at the earliest.
Regards,
Pradip Kumar Das
