I have an Acer TravelMate B1, model TMB118-M-P98A. The acer_wmi module loads and all Fn keys except the Fn+F3 WiFi key (Airplane mode, turn on/off the network devices) work one way or another (either out of the box or they are recognized as XF86 keys). Fn+F3, however, only generates the following kernel message: acer_wmi: Unknown function number - 2 - 1 Is there a chance to treat this function number in the driver as WMID_HOTKEY_EVENT for KEY_WLAN and KEY_BLUETOOTH? (By the way, the touchpad toggle Fn+F7 already works out of the box). If allowed, I can post my DSDT. I can also test possible patches.
