Subject: drm/i915/vlv: reduce GT FIFO error info to a debug message
It indicates a probable BIOS bug, but it appears to be harmless, and
there's nothing the user can do about it anyway, so reduce to a debug
msg. I've filed a bug with the BIOS folks about it anyway, so hopefully
they'll fix whatever GT SB read they were doing when the GT was off.
