As far as I know, the differences between linux-lts and linux-vfio-lts package are (I hope Dan can confirm this?):
1. Intel HD VGA Arbitration patch and PCIe ACS Override patch

Probably there’re some kernel config in linux-lts that made the OVMF hang in your setup?
What happens if you do not passthrough any host USB. If you have one, try passing through a whole USB PCIe Controller?
Another alternative is to use Mark Weimann’s repository  to install a precompiled version of linux-vfio and linux-vfio-lts kernel package.
