I'm trying to bring up F9 on an Asus M3A78-T (a relatively new AMD Phenom-x4 capable board). Going through /var/log/messages I see that the kernel doesn't think the BIOS enabled the IOMMU and gripes about it. Googleing a bit found me a magic parameter to add to grub.conf, "iommu=memaper=4". That gets me a new error message preceding the former: "kernel: Aperture pointing to e820 RAM. Ignoring.". I do have over 4g of dram, so having a bounce-buffer sounds important, but I'm plumb out of ideas. Is there a slower fallback the kernel is using (like purely software moves???) for systems that don't have a working IOMMU? -wolfgang -- Wolfgang S.
