I can not see a 05:01.0 using lspci. There is however 05:0e.0, which is the RAID controller (Adaptec RAID 3405). It's kind of a critical component, so I can not disable it. ;) Does this mean, it's impossible to make IOMMU work on this machine?
Try booting the system without intel_iommu=on, but with the IOMMU enabled in the bios. Something has to be at 05:01.0. Do you see any Ricoh devices anywhere in lspci output?
