I have been experiencing similar issue when rebooting or shutting down a Windows 10 VM with a RTX 2070 Super and motherboard USB controller passed through.
I added pcie_no_flr to my syslinux.cfg as suggested here blindly and noticed no difference. I then took the time to read and understand the thread and realised it was a specific pci-e address and looked up the correct address for my own USB controller which I found from Tools > System Devices. I have reset, hibernated, rebooted and powered offthe VM since and with fingers-crossed no issue so far.
Just thought I'd post this here in case anyone else has similar issues on different hardware and is as slow on the uptake as I am.
System hangs when VM Changes states (shutdown, restart etc)
in Stable Releases
