The exact problem is that an IRQ/ACPI workaround is not needed anymore on modern Zen platforms, and it (the workaround) now breaks compatibility. It's already in linux master, and will be released for v6.0

ACPI: resource: skip IRQ override on AMD Zen platforms
IRQ override isn't needed on modern AMD Zen systems.
There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay
this way on newer platforms. This IRQ override breaks keyboards for
almost all Ryzen 6000 laptops currently on the market.
Skip this IRQ override for all AMD Zen platforms because this IRQ
override is supposed to be a workaround for buggy ACPI DSDT and we can't
have a long list of all future AMD CPUs/Laptops in the kernel code.
If a device with buggy ACPI DSDT shows up, a separated list containing
just them should be created.
Some vendors may only 'test' as far as getting the compiler to produce something without errors. So, first thing an end-user/consumer/enterprise customer can do when encountering a new platform is to run the platform through https://uefi.org/testtools, in particular the FWTS/Firmware Test Suite and SCT/ACPI Self-Certification Test, and hold the vendor accountable. Chances are the vendor already has a member on the board of the Unified Extensible Firmware Interface Forum.
