> interesting, we didn't find this in nivviks I think :)

The interrupt storm only happens with ITE ECs, not Nuvoton. I think changing it to edge triggered is correct regardless based on the spec linked from b/308539814#comment11: https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/12_ACPI_Embedded_Controller_In... But there is still something unexplained about the ITE vs nuvoton behaviour.

Also I tested that wake still works on craask with this change.
