If I remember correctly, acpi_hp worked on 8.0-RELEASE. When loaded via loader.conf, there is no /dev/hpcmi, sysctl dev.acpi_hp returns 0 lines. Unloading and loading the module make it work again. I've already tried to build a custom kernel with both acpi_wmi and acpi_hp compiled in - same problem as loaded on boot. >How-To-Repeat: Boot the machine with acpi_hp_load="YES" in loader.conf: - no device entry /dev/hpcmi - empty output of sysctl dev.acpi_hp then, reload the module: kldunload acpi_hp && kldload acpi_hp - /dev/hpcmi present and readable - sysctl dev.acpi_hp returns values described in acpi_hp(4) >Fix: >Release-Note: >Audit-Trail: >Unformatted:
