Re: Intel SE7500WV2 not working with ACPI (fwd)

[Nate Lawson <nate-Y6VGUYTwhu0@public.gmane.org>]

I can't figure this one out.  I think the issue is that various methods
are defined under device "EC0" (note 3 chars) but when ACPI-CA attempts to
call _REG, some internal function expands the name to "EC0_" (note 4
chars), which doesn't exist.

Ideas?

Thanks,
Nate
