I do know this laptop has a buggy DSDT but I have never had luck in 
trying to get the errors fixed. I can never find things online in 
relation to the errors it produces, best I have ever done is clear 2 of 
the 200 something errors when trying to recompile it :P

I guess that must be it though the BIOS not playing nice, just weird it 
only shows on the Arch kernel. Maybe I need to finally figure out how to 
do my DSDT.
