| 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. |
