how do you know the event is sent via ACPI?

please try "cat /proc/interrupts > interrupt-1;
grep . /sys/firmware/acpi/interrupts/* > gpe-1; sleep 5;
cat /proc/interrupts > interrupt-2;
grep . /sys/firmware/acpi/interrupts/* > gpe-2", and press the block key
during the 5 seconds sleep.
Then please attach the 4 files here to see if there are ACPI interrupts
generated by the key pressing.

thanks,
