Comment 6 for bug 724569

It's raw output from the kernel before plymouth is even loaded. downgrading it from dev_err to dev_info suppresses it as well.

The problem in this bug is that the error is emitted even if i915 isn't used at all and it stays on the screen during a text mode plymouth boot. the patch in manjo's kernel just makes it attempt relinking to i915 again for the people getting the error that are actually using intel graphics, and the actual error still shows up at the beginning too with it.
