Maybe. intel-gfx at lists.freedesktop.org might be more appropriate since
this is a kernel driver bug.

What this is saying is the driver had some expectations about the state

expectations were violated. If there's no functional problem you can
safely ignore it, but it's a kernel driver bug either way.
