https://bugzilla.kernel.org/show_bug.cgi?id=81841 --- Comment #13 from Marti Raudsepp <marti@xxxxxxxxx> --- (In reply to Joerg Roedel from comment #12) > Thanks, Joerg 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.

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.
