Yes, I had a look at the dmesg and went through the code again. I have
no clue yet why that commit causes the issue on your machine. Between
the two places in the code where the set_root_entry calls are/were,
there are no other things going on with the iommu hardware, so it
shouldn't matter when setting the root entry happens earlier.
Can you try to track down (with some debug code) exactly where it is
hanging? That might bring some more light into the issue.
