I was looking over a dmesg output and I noticed a message that said I would
save 64MB of RAM if I enabled the IOMMU option in the bios.


Can anyone eleborate on this message in dmesg?

A post that tries to elaborate is at<http://bogdan.org.ua/2009/09/30/iommu-this-costs-you-64-mb-of-ram.html>.

I had other symptoms as well, and used iommu=soft as boot option for awhile, but if you do not see any other problems relating to iommu, Iwould ignore it.
