Failed to open BO for returned DRI2 buffer (1366x749, dri2 back buffer, named 6).
This is likely a bug in the X Server that will lead to a crash soon.

This most likely relates to the updates to the i915/intel support in the linux kernel.

This will also be cross reported to the kernel maintainers if someone can confirm my suspicion that it is indeed the updates to the i915 kernel module causing it.

I have the same problem. I’ve downgraded to xf86-video-intel 2.99.917-5. It looks like a bug in Intel video driver.

Right, given that this bug was introduced in a change correlated with the 4.0.7 kernel I’ll report it to upstream developers, thank you for verifying.
Most likely the relevant entity is the foundation, perhaps linux kernel maintainers as some of their work touches on the i915 support.
