Yes this is the version I currently have.

What I meant was where is the hardware initialize at
(for the prefetch decode), this code is working as far
I could tell. The prefetch decode in the hardware is
set to 0.

Would any body know if following errors could be causing the failure?
acpi0: reservation of 0, a0000 (3) failed
acpi0: reservation of 100000, 7f00000 (3) failed
