Comparing the dmesg with my kernel log, I'm missing messages like [ 0.023960] DMAR: Host address width 36 [ 0.023962] DMAR: DRHD base: 0x000000fed90000 flags: 0x0 [ 0.023968] IOMMU 0: reg_base_addr fed90000 ver 1:0 cap c9008020e30272= ecap 1000 [ 0.023970] DMAR: DRHD base: 0x000000fed93000 flags: 0x1 [ 0.023974] IOMMU 1: reg_base_addr fed93000 ver 1:0 cap c9008020630272= ecap 1000 [ 0.023976] DMAR: RMRR base: 0x000000bf6e9000 end: 0x000000bf6fffff [ 0.023978] DMAR: No ATSR found about the Intel DMAR (IOMMU) setup. Are you sure that you have an Intel chipset with the required features? And have you checked that "VT-d" is enabled in the BIOS (or however it may be called there)?
