I had a very similar bug report: ________________________________________ The ACPI events, which are triggered by keyboard (via Fn key, eg. to switch WiFi card on/off) are somehow buffered in the kernel. I have to push the key combination 8 times until acpi_listen (or cat /proc/acpi/event) gets the first event, then, if I push other combinations, I get the events from the "buffer". ________________________________________ EC burst mode did solve this problem on that machine.
