  qemu Windows 7 BSOD when using hv-time

Status in QEMU:

Bug description:
  When I use hv-time sub option and run CPU-Z or 3DMark (Physics Test)
  the Windows 7 guest stops with BSOD (SYSTEM_SERVICE_EXCEPTION). It can
  be easily reproduced by running CPU-Z. It will fail every second or
  third time you execute CPU-Z and fail during "PCI detection". If I
  disable hv-time I can run CPU-Z and 3DMark (Physics Test) without any
  problems. QEMU was called with the following options:

  /usr/bin/taskset -c 4,5,6,7 /usr/bin/qemu-system-x86_64 \
   -machine q35,accel=kvm,kernel_irqchip=on \
   -enable-kvm \
   -serial none \
   -parallel none \
   -monitor none \
   -vga std \
   -boot order=dc \
   -cpu host,hv-time \
   -smp cores=4,threads=1,sockets=1 \
   -m 8192 \
   -k de \
   -rtc base=localtime \
file=/srv/kvm/maggie-drive0.img,id=drive0,if=none,cache=none,aio=threads \
   -mon chardev=monitor0 \
   -chardev socket,id=monitor0,path=/tmp/maggie.monitor,nowait,server \
   -netdev tap,id=net0,vhost=on,helper=/usr/lib/qemu/qemu-bridge-helper \
   -device virtio-net-pci,netdev=net0,mac=00:00:00:02:01:01 \
   -device virtio-blk-pci,drive=drive0,ioeventfd=on \
   -device ioh3420,bus=pcie.0,id=pcie0,port=1,chassis=1,multifunction=on

  I've removed the VFIO PCI passthrough line of my GPU to make
  reproduction easier. In any case it happens in both scenarios so VGA
  passthrough is not the root cause. It happens with linux-3.15-rc5 and
  linux-3.14.3 with patch from commit mentioned at
