Odd.  Did this happen in 2.6.29?

If so - I think there's only one significant EC change since 2.6.29,
you could try reverting that.

I have seen something similar with different kernels.  See for example
https://bugzilla.redhat.com/show_bug.cgi?id=492699
which reports that for kernel-2.6.27.19-170.2.35.fc10 and
kernel-2.6.29-3.fc10 Fedora kernels and Asus Eeeps 1002HA.

https://bugzilla.redhat.com/buglist.cgi?quicksearch=+Method+parse%2Fexecution+failed

brings a list where it is possible to find something of that sort
in different settings too.

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:

<http://bugzilla.kernel.org/show_bug.cgi?id=12949#c20>

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.

Hm, at least https://bugzilla.redhat.com/show_bug.cgi?id=472650#c5
seems to be quite similar.  It says:

ACPI Error (evregion-0315): No handler for Region [EC__] (f780b848)
[EmbeddedControl] [20080609]
....
and so on.  That is for GX700 laptop from MSI.

I did not go through every of those reports from the referenced list.
