If linux is running as a guest and the host is doing igd pass-through with VT-d enabled, this message is logged dozens of times per second.

The i915 driver should also detect VT-d in this case, but that is a different issue. I have sent a separate mail with subject 'Detecting Vt-d when running as guest os'.
