Hi all!
I've just recently noticed these lines in the dmesg output:
Please enable the IOMMU option in the BIOS setup This costs you 64 MB of RAM
they may have been there forever, but I never noticed them before. This system is an AMD Phenom-II X2 CPU on a Gigabyte MA770-UD3 motherboard.
I have no idea which BIOS option I need to change to solve this, I see nothing in the setup that refers to IOMMU.
Clues, please?
thanks!

The IOMMU supports I/O virtualization. As far as I can tell your motherboard's chipset does not implement an IOMMU, they're not all that common on desktop systems.
You can probably just ignore this message.
