maybe you need to reinstall

You shouldn't need to, just hook a USB keyboard to unlock the disk, and follow the instruction should be fine.

Same experience here. Added everything to my MODULES, but no luck. I always need to unlock via external keyboard.

Update: I got it working and have this in my mkinitcpio.conf:

MODULES=(btrfs i915 surface_aggregator surface_aggregator_registry surface_aggregator_hub surface_hid_core 8250_dw surface_hid surface_kbd intel_lpss intel_lpss_pci pinctrl_tigerlake)

OK finally got this working.
For anyone running ubuntu 22:

1. Edit /etc/initramfs-tools/modules
2. Add the following module lines to the file:

btrfs
i915
surface_aggregator
surface_aggregator_registry
surface_aggregator_hub
surface_hid_core
8250_dw
surface_hid
surface_kbd
intel_lpss
intel_lpss_pci
pinctrl_tigerlake

if I not missed something

# FS not need for KBD to work
btrfs
# driver module not need for KBD to work
i915

Good Morning.

I'm having the same issue with SGO 1st gen. ¿Can someone help me? It's also happening on the Operating system intermittently. Seems a kernel issue as it happens on the stock Distros Kernels.

For anyone else who winds up here via google, I needed something to do with my hands while watching Mystery Men today, started with dumping the contents of lsmod into my MODULES=() and whittled it down to this minimum set:

MODULES=( 8250_dw intel_lpss_pci surface_hid surface_aggregator_registry usbhid vfat )

removing any of those makes my SL4's keyboard not work for luks passphrase entry.
