Comment 26 for bug 859137

@rushack: if the problem truly is the same as this issue tracks then the only solution is to turn off the IOMMU feature of your BIOS settings. unfortunately this means that any software that relies on IOMMU (mostly KVM or Xen) will fail to provide the features it supplies.

IOMMU is mainly used to improve speed and compatibility of some hardware accesses by virtualisation utilities such as intel's server ethernet adapters - VMDQ and SR-IOV.
