[Qemu-discuss] vfio: hang enabling interrupts with OVMF with latest qemu git master

[Bruce Cran]

I just built qemu from the latest git master 
(0975b8b823a888d474fa33821dfe84e6904db197) and have found that OVMF x64 
(using qemu-system-x86_64) has stopped working. It hangs in 
SetInterruptState() when calling EnableInterrupts().   I have a single 
PCIe device passed through using VFIO.

I built it with gcc version 6.2.1 20160830, configured with:

./configure --prefix=$HOME --enable-sdl --enable-kvm --enable-linux-aio 
--enable-vhost-net --enable-spice --enable-vnc --enable-system 
--disable-smartcard --disable-tpm --disable-libssh2 --disable-curses 
--disable-libusb --disable-usb-redir --disable-xen   --disable-bluez 
--disable-user --disable-vde --target-list=x86_64-softmmu,aarch64-softmmu

Is this a known problem, or should I submit a bug report?
