Public bug reported:
Since commit 5e95494380ec I am no longer able to passthrough my Nvidia
GTX 770 using VFIO. Qemu terminates with:
qemu-system-x86_64: hw/pci/pcie.c:240: pcie_cap_slot_hotplug_common:
Assertion `((pci_dev->devfn) & 0x07) == 0' failed.
Above output was generated using commit f55ea6297cc0.

hw/pci: switch to a generic hotplug handling for PCIDevice
make qdev_unplug()/device_set_realized() to call hotplug handler's
plug/unplug methods if available and remove not needed anymore
hot(un)plug handling from PCIDevice.
In case if hotplug handler is not available, revert to the legacy
hotplug method for compatibility with not yet converted buses.

commit 6e1f0a55a14bad1d0c8b9d29626ef4e4b2617c74
Author: Igor Mammedov <imammedo@redhat.com>
Date: Mon Feb 17 15:00:06 2014 +0100
PCIE: fix regression with coldplugged multifunction device
PCIE is causing asserts each time a multifunction device is added
on command line (coldplug).
This is caused by
commit a66e657e18cd9b70e9f57ae5512c07faf2bc508f
pci/pcie: convert PCIE hotplug to use hotplug-handler API
QEMU abort is caused by misplaced assertion, which should
be checked only when device is hotplugged.
Reference to regression report:
http://www.mail-archive.com/qemu-devel@nongnu.org/msg216226.html
Fixes: a66e657e18cd9b70e9f57ae5512c07faf2bc508f
