Seems 0f:00.0 is not attached to a group so that it get a domain. Can
you also paste your "lspci -t" and "lspci -vvv" output? Here 0f:00.0
should be a pci bridge which need set the same domain with its
peripheral 0000:0f:04.0.
Please apply this patch and try again.

Subject: [PATCH] iommu/amd: Correct the wrong setting of alias DTE in
do_attach

is setting DTE. But there's a code bug here to wrongly set the
alias DTE, correct it in this patch.
