Sorry for spamming, just want to add info for Linux kernel version.

I am using Linux mainline kernel 5.0-rc7 with the latest commit:

commit a215ce8f0e00c2d707080236f1aafec337371043 (origin/master, origin/HEAD)

    Merge tag 'iommu-fix-v5.0-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

    Pull IOMMU fix from Joerg Roedel:
     "One important fix for a memory corruption issue in the Intel VT-d
      driver that triggers on hardware with deep PCI hierarchies"

    * tag 'iommu-fix-v5.0-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
      iommu/dmar: Fix buffer overflow during PCI bus notification

[...]

Thanks,
