Hi,
	intel_iommu was briefly enabled by default in Fedora rawhide.

	One user reported lots of error spew like:

   DMAR:[DMA Write] Request device [03:00.0] fault addr fff8d000 
   DMAR:[fault reason 05] PTE Write access is not set

	followed by filesystem corruption. We've made intel_iommu=off the
default now.

	Details here:

  https://bugzilla.redhat.com/328997

	Any of the maintainers interested in working with the reporter to sort
this out?

Thanks,
Mark.
