_with_ that patch?

It very much replaces a warning with no further info with

+                       WARN_ONCE(pci_dev->current_state != prev,
+                               "PCI PM: Device state not saved by %pF\n",
+                               drv->suspend);

And notice the "%pF" and the 'drv->suspend': it should tell you exactly 
which suspend routine it was that messed up.
