Hi,

Looping in debian-kernel@, context being missing touchpad support on an
amd64 machine, unless an extra module is added to the installer.

Feel free to steal the bug report away from us and adjust
debian/installer/modules as you see fit!

Checking linux.git, it seems pinctrl modules are only shipped in udebs
for a single arch:

    kibi@tokyo:~/debian-kernel/linux.git (debian/6.12/trixie <)$ git grep pinctrl -- debian/installer/
    debian/installer/modules/arm64/kernel-image:drivers/pinctrl/**

I'm not sure how many pinctrl modules would make sense to ship, or in
which udeb, for other architectures.

Looking at the amd64 config, the modular ones are:

    CONFIG_PINCTRL_ALDERLAKE=m
    CONFIG_PINCTRL_CS42L43=m
    CONFIG_PINCTRL_ELKHARTLAKE=m
    CONFIG_PINCTRL_EMMITSBURG=m
    CONFIG_PINCTRL_INTEL_PLATFORM=m
    CONFIG_PINCTRL_JASPERLAKE=m
    CONFIG_PINCTRL_LAKEFIELD=m
    CONFIG_PINCTRL_METEORLAKE=m
    CONFIG_PINCTRL_METEORPOINT=m

while the built-in ones are:

    CONFIG_PINCTRL_AMD=y
    CONFIG_PINCTRL_BAYTRAIL=y
    CONFIG_PINCTRL_CHERRYVIEW=y
    CONFIG_PINCTRL_INTEL=y
    CONFIG_PINCTRL_BROXTON=y
    CONFIG_PINCTRL_CANNONLAKE=y
    CONFIG_PINCTRL_CEDARFORK=y
    CONFIG_PINCTRL_DENVERTON=y
    CONFIG_PINCTRL_GEMINILAKE=y
    CONFIG_PINCTRL_ICELAKE=y
    CONFIG_PINCTRL_LEWISBURG=y
    CONFIG_PINCTRL_SUNRISEPOINT=y
    CONFIG_PINCTRL_TIGERLAKE=y
