Indeed. Thanks, Joerg. And thanks everyone else too, you have been very
helpful!
I didn't have v3.13 sources handy, but I applied the attachment 146311 patch to
3.16.0 and it fixes the problem. (I verified that unpatched 3.16.0 also
crashes).
I can start & shut down the VM multiple times without crashing the host and PCI
passthrough works as expected.
Feel free to add

This approach also works; I think I will go this route for the production
setup. Seems that we don't actually need any of the devices in the same IOMMU
group.

I am sorry if I sounded frustrated or arrogant earlier. Any update on this?
