Hi,
Since v6.5-rc1 the keyboard on this laptop no longer works. This problem
also existed before v6.0-rc1 commit 9946e39fe8d0 ("ACPI: resource: skip
IRQ override on AMD Zen platforms"), so I suspected the cause to be
a9c4a912b7dc ("ACPI: resource: Remove "Zen" specific match and quirks")
which reverted that commit. Reverting a9c4a912b7dc confirmed this theory.
#regzbot introduced: a9c4a912b7dc
My specs are:
Laptop model: Lenovo Yoga 7 14ARB7
BIOS: K5CN40WWT66 (latest beta from [1])
CPU: AMD Ryzen 5 6600U
Kernel config: [2]
Distribution: Arch Linux
The issue has been confirmed by at least one other user with this
laptop: [3]

This is unfortunate. Before we go adding more quirks for your system,
can you please check for a BIOS upgrade for your system? If it's
happening with the latest BIOS, then can you please open a kernel
bugzilla with an acpidump and dmidecode included?

The latest released BIOS is K5CN40WW, I'm using K5CN40WWT66 which is a
later beta that partially mitigates a Windows BSOD issue. I've opened a
Bugzilla report with the dmidecode here:
https://bugzilla.kernel.org/show_bug.cgi?id=217718
For the acpidump I'm not sure what parts could be sensitive so I will
e-mail it directly to you.
