Hey @Kruptein! Your gist is one of the few places on the internet that's showing the same hang I'm getting in acpi_ec_event_processor on my laptop. On my machine this results in everything that tries to access the ACPI infrastructure failing from this point on, which means no more suspending my laptop, amongst other things.

I don't suppose you found the cause of this, or better still a fix?

Many thanks in advance!
