You also missed dmesg output (from both v5.16.y and v6.4.y). Thorsten also asked you to bisect. Since you're on Gentoo, there is a wiki article on this [1]. To narrow the bisection range, let me ask this question: Does v6.1 kernel have this regression? What about v5.17? In any case, the kernel documentation also have howto on building custom kernel with trimmed config [2]. Anyway, I'm adding this regression to be tracked by regzbot: #regzbot ^introduced: v5.16..v6.4 #regzbot title: Thinkpad L14 Gen 1 keyboard not working on Plasma session Thanks.
