Subject: Re: ACPI errors with 3.7-rc3

I'v also have such errors on my macbook pro.

$ dmesg | tail

And also loadavg is too high ~ 10
While there is no process that load CPU up to 100% or like that.
I think that this because of processes that is done in kernel space.
(basically that one who write such errors)
