The behavior was observed with Lenovo ThinkPad C13 Yoga.

This driver should not get loaded in chrome OS by default.
Could you please provide details of Chrome OS Version and Kernel version to confirm the behavior.

Are you enabling manually CONFIG_AMD_SFH_HID config?


I use Fedora 36, not Chrome OS. The config is enabled on Fedora's generic kernel. The kernel is built from commit 78ca55889a549a9a194c6ec666836329b774ab6d from the upstream.
