Not sure what could be causing this exactly. Have you compiled your kernel with CONFIG_INTEL_IOMMU (a bit of a blind shot to be honest, but it's the first time I see something like this logged)?

Thanks,

Any chance iommu support could simply be removed from the driver so that we don't have to disable iommu for the kernel? Note that currently it's impossible to use a DisplayLink adapter on a system that is passing through devices to VMs.
