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

[    0.023970] DMAR: DRHD base: 0x000000fed93000 flags: 0x1
[    0.023974] IOMMU 1: reg_base_addr fed93000 ver 1:0 cap c9008020630272 ecap 1000

[    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)?
