After commit 1a699476e258 [two months ago], Linux has stopped recognizing the media & function keys on my laptop's keyboard (the laptop is ASUS K52JT.206).
When I press any of the Fn keys (Play/Pause, Stop, Prev, Next, Vol+, Vol-, Mute, WiFi, Brightness +/-...), I get the following messages in dmesg: | ACPI: \_SB_.ATKD: Unsupported event type 0x45 | ACPI: \_SB_.ATKD: Unsupported event type 0x43 | ACPI: \_SB_.ATKD: Unsupported event type 0x40 | etc. In the past (v3.14 and earlier), those used to be reported as ACPI and input events. From `acpi_listen` on a good kernel: | hotkey ATK0100:00 00000045 00000000 | cd/play CDPLAY 00000080 00000000 K | | hotkey ATK0100:00 00000031 0000000d | button/volumedown VOLDN 00000080 00000000 K | | hotkey ATK0100:00 00000016 00000000 | | hotkey ATK0100:00 00000025 00000001 Bisect output: 1a699476e25814343766342672c655fb135224cc is the first bad commit commit 1a699476e25814343766342672c655fb135224cc Author: Rafael J. Wysocki <[email protected]> Date: Thu Feb 6 13:58:13 2014 +0100 ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify() Since acpi_bus_notify() is executed on all notifications for all devices anyway, make it execute acpi_device_hotplug() for all hotplug events instead of installing notify handlers pointing to the same function for all hotplug devices. [...] * Linux 3.14.0-rc1-00023-g1a699476e258 (bad) * Linux 3.14.0-rc1-00022-g5e6f236c2631 (good) (I'm not quite sure why they show up as 3.14-rc1 if they're after 3.14?) The kernel config is close to that of stock Arch Linux, except with entirely irrelevant devices disabled (PATA, SCSI, tuner, etc.) -- Mantas Mikulėnas <[email protected]> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
