Could you please help to enable acpi debug log? acpi.debug_level=0x2 acpi.debug_layer=0xFFFFFFFF Please attached dmesg and messages log that cover system boot and pressed brightness key a couple of times. And, Please also monitor does there have any value of gpe was increased when you press brightness keys: watch -n 1 cat /sys/firmware/acpi/interrupts/gpe[012][0123456789ABCDEF] Please tell me which gpe's value increased if you found. Thanks a lot!
