GPU crash dump

While booting, I get this error:

I can still play 3D games, with very some minors and graphic glitches. But I'm doing the report anyway. Attached is the GPU crash dump.

Here is everything related to the i915 driver:

This is a GPU page fault during KMS takeover (the display engine is still trying to read the scanout left over by the BIOS, but the PTE no longer match). This should be fixed in 3.18+.
