CLEVO B5120 acpi problems, probably EC-related

[Oliver Freyd]

Hello,

I'm trying to get this new laptop running with linux (debian testing)
most things are working well, I get acpi events for hotkeys
like volume up/down, or light up/down, but no acpi_events
or even interrupts for the sleep button, the power button,
lid switch and AC power plug.

especially strange I find the "EC GPE storm detected" and the 3 
AE_NOT_FOUND errors.
I tried to decompile the DSDT, and was able to compile it back after 
fixing some rather trivial errors, but I'm at a loss with the missing 
methods.

I also tried a 2.6.36rc1 kernel, compiled from source,
the missing methods in dmesg were gone, but the buttons did not
work either...


lots of fun hacking linux,
