Install of latest Parallels Tools did the trick!
After the second (or was it third?) reboot and installation of the new version of the Parallels tools (which crashed twice), the PCI issue is gone, as others have noted.
Hope that helps others.
BTW... I'm a little concerned about the stability of this release. I'm seeing some odd behaviour (including a system freeze, which NEVER happens on my MBP). Good luck, all!
