From: Charles Kroeger on 16 Mar 2010 14:30 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. I'm using an ASUS M4A79XTD EVO board with 8GB of RAM so maybe freeing up 64MB of RAM isn't that big of a deal; however, I had a look in the bios setup and saw nothing that pertained to IOMMU to enable. The BIOS is an 8MB Flash ROM, AMI BIOS PnP etc. Can anyone eleborate on this message in dmesg? -- C -- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I had other symptoms as well, and used iommu=soft as boot option for a while, but if you do not see any other problems relating to iommu, I would ignore it. / johan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
