--- Comment #8 from Alex Williamson <[email protected]> --- Unless you're trying to do PCI device assignment, KVM doesn't have any dependency or interaction with the IOMMU. General IOMMU issues would probably be better served reporting them to the IOMMU mailing list:
https://lists.linuxfoundation.org/mailman/listinfo/iommu
If you are attempting to do PCI device assignment, please provide details including VM configuration (XML or qemu launch scripts) and dmesg prior to the AMD-Vi spew.

--- Comment #12 from Chesn <[email protected]> ---
FWIW, setting
iommu=soft
got rid of the journal spam in my case (found here)
full disclosure: i don't care about virtualisation (i only ever messed around with it to check out gnome boxes) and i've disabled kvm and kvm_amd (even blacklisted the modules in a file /etc/modprobe.d/blacklist_kvm.conf), even disabled virtualisation in BIOS while debugging this issue (none of which worked)…
good luck with fixing this, guys!
regards,
M.

iommu/amd: Don't clear DTE flags when modifying it
During device assignment/deassignment the flags in the DTE get lost, which might cause spurious faults, for example when the device tries to access the system management range. Fix this by not clearing the flags with the rest of the DTE.
Can anyone mark this resolved?
