Cool, thanks for the info, As of right now I'm mainly trying to clean
up as much acpi errors that I can
find in my system, in hopes leading me to more info on fixing a bug(or
someone else).: http://bugzilla.kernel.org/show_bug.cgi?id=10724
For right now I have cleaned up all of the errors and warning from the
dsdt.dsl and have
plugged in the new dsdt.hex into the kernel.(everything seems O.K).,
except for two messages I received
from running iasl
i.g. I've google but found not very many results for this
No back ptr to Op: type 8
No back ptr to Op: type 8

After contemplating I decided to go ahead with the modified dsdt
irregardless of the: No back ptr to Op: type 8
message, but to my dismay I'm still receiving the BUG. "gripes"
on a positive not creating a custom dsdt and loading it into the
kernel is "cake", figuring out how to fix the dsdt is a "bi*^h";
anyways If you or anybody knows what this means, please send a message.
