| |
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]
