As several module parameters using the same ACPI prefix are defined in the different files(for example: power_nocheck is defined in drivers/acpi/power.c,debug_layer/debug_level are defined in drivers/acpi/debug.c) and there exists another module between them, the warning message will be printed when using the current generic param code. (In the function of param_sysfs_init). In fact when ACPI is selected, the drivers/acpi/power will also be compiled as built-in kernel.So this issue can be fixed by the following approach. workaround it by adjusting the module link order in drivers/acpi/Makefile. In such case the module parameter using the same prefix(ACPI) are put together in the param data section. Of course the better solution is to fix it in generic param code related with sysfs.

It exports the backlight via the backlight class device API, and the hotkeys as input event device. Some more esoteric items like number of installed batteries are exported via sysfs device attributes. Hotkey events also generate old-style ACPI enents through /proc/acpi/event to interoperate with current versions of acpid.

For safety reasons, only the PWM OFF (fan at 100%) or maximum closed-loop level (level 7) are preserved. If the fan state was set to anything else, it will not be restored. Also, should the fan be at PWM OFF mode at resume, it will be left at that state (but this is extremely unlikely, no ThinkPad firmware was ever reported to do this). For reference, the known states used for fan control upon resume by the firmware are either "auto" or "level 7" depending on whether the laptop wakes due to normal conditions or a thermal emergency.
