Well... I was looking if BIOS options of the motherboad (M2N32 SLI Deluxe) had some reference to IOMMU, but I found nothing. According to a post [1] I read on the list, I tried the option amd_iommu=3Don, obtaining the following in the log: # dmesg | grep -i iommu [ 0.000000] Command line: BOOT_IMAGE=3D/boot/vmlinuz-2.6.39-bpo.2-amd64 = root=3DUUID=3D084f271f-0d70-40d2-9c22-c38848cd4d82 ro amd_iommu=3Don quiet [ 0.000000] Kernel command line: BOOT_IMAGE=3D/boot/vmlinuz-2.6.39-bpo.2= -amd64 root=3DUUID=3D084f271f-0d70-40d2-9c22-c38848cd4d82 ro amd_iommu=3Don= quiet [ 0.000000] Please enable the IOMMU option in the BIOS setup [ 0.654633] PCI-DMA: using GART IOMMU. [ 0.654638] PCI-DMA: Reserving 64MB of IOMMU area in the AGP aperture For the message "Please enable the IOMMU option in the BIOS setup", it seems that IOMMU is still not enabled. So maybe you were right in what you said before.
