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.  

My hardware:

MB: ASRock X99 Extreme4
CPU: i7-5930k
Mem: 32 GB
Host GPU (prev. used for guest): AMD R9 280x [1002:6798] (hybrid vga/uefi)
Guest GPU: AMD R9 290x [1002:67b0] (switchable vga / uefi)
Prev. Setup Host GPU: AMD HD 7850 (vga only)
Host OS: Arch Linux - Kernel 4.1.13
Guest OS: Win 8.1

Attached file lspci.txt contains lspci -nnvvv output for all devices
related to passthrough.

Attached file games.xml is the libvirt config for my VM.
