Hello,
After upgrading from 6.11 to 6.12 a bunch of Fn+Fx buttons(touchpad,
mic, kb backlight, my asus) stopped working and the
/sys/(...)/asus::kbd_backlight interface is missing, which, considering
the dmesg, looks like an asus-wmi driver issue.
I've been able to bisect the issue to the commit
[b012170fed282151f7ba8988a347670c299f5ab3] "platform/x86: asus-wmi: Fix
thermal profile initialization"
Additionally, here's some maybe-helpful information:
my laptop's model -- ASUS Zenbook UX3402VA
linux distro -- Arch Linux
.config for bisection -- was taken from /proc/config.gz at 6.12.1 arch
kernel(attached in [1]) and missing options are default
dmesg logs -- The "grep asus" parts of both good and bad scenarios can
be seen below and full logs are at [2] and [3]
