659 This was reported by a user, running Debian 11 with
660 kernel `5.19.0-0.deb11.2-amd64`. The `thinkpad_acpi` module was not loading,
661 with the following message:
659 Reported by a user on Debian 11 (on a ThinkPad T440p) and a user
660 on Void Linux (ThinkPad T480), Linux may fail to load `thinkpad_acpi`.

664 * [ThinkPad W541](https://libreboot.org/docs/install/w541_external.html)
665 * [ThinkPad T440p](https://libreboot.org/docs/install/t440p_external.html)

668 This may result the following effects, including or not limited to:
666 669
667 Battery info in `/sys` was absent, because of this. The user reported that
668 the following workaround was effective (in Debian).
670 * Temperature reporting not working
671 * Battery info not working.
672 * Fan speed reporting not working
673 * Fan control not working
