Hi!
I have looked at your DSDT table which you sent me months ago and I see
that your ACPI code does not clear WMI buffer before sending it to OS
driver (buffer named INFO, and u16* values in INF0, INF1, ... INF7).
And I see that your ACPI code always send one "message" in WMI buffer,
not like on my E6440 when I receive one "message" for keypress event and
appended "message" that keyboard backlight was changed.
Because your ACPI code does not clear buffer before filling it, it is
impossible to parse correctly on both machines (my and your)... :-(
But I see that on your machine ACPI set "WMI Interface Version" to 0x0.
On my machine and Michał's too it is set to 0x1. (See ACPI-WMI%20.pdf)
So maybe this information is important?
Anyway your ACPI DSDT code contains all possible WMI events (for your
machine) as they are generated by ACPI and not by EC/firmware...
