Interesting.  Not the same model, but both are relatively new.  It
sounds as if they switched to the EC chip that Acer used for the
Aspire One :-).  There's a very similar bug for the Acer netbook:

<http://bugzilla.kernel.org/show_bug.cgi?id=12949>

There are several patches.  Alexey's patch was confirmed to help on
the Acer netbook.  I suggest you try the latest patch from Alexey,
which is attached at comment 20:

I think that's a very general failure message, that ACPI failed to
execute some method.  I don't think there are any other EC (Embedded
Controller) failures on that list.
