I recently got myself a "new" (used) gpu to replace the one I was previously using for passthrough with vfio, and I discovered a strange bug during this. With the new GPU being passed through to the guest, the host will "sort of" crash on guest shutdown. Video output freezes and all usb devices seem to stop working, but ssh access still works fine. virsh cannot be accessed over ssh though, it just hangs. There is a stack trace printed in dmesg, but I don't think this is the same each time. See the most recent one at the bottom.
My VM is set up to use 8 1GB sized hugepages for memory. By disabling hugepages completely, or switching to 4096 2MB hugepages, the crash is eliminated and the guest can be shutdown or reboot as much as I want. I'm not sure what can actually be done about this, but I though it would be a good idea to at least document it here. This same setup with 1GB hugepages worked just fine before upgrading the GPUs. One noticeable difference between the GPUs is the the 280x I was previously using as the guest gpu had a bios that supported both legacy vga and uefi, while the new 290x has two bioses that can be chosen with a physical switch - one legacy vga and one uefi. My old 7850 host gpu only supported legacy vga, so I had to leave the CSM module enabled in my firmware. Now that that is gone, I tried switching to pure UEFI boot for the host by disabling the CSM module, but that does not help with the error on guest shutdown.
