Hmm. It's almost certainly one of the DRI patches, but which one? I
think bisection is the only way to figure it out. It shouldn't be too
bad, since there's only 120 commits in that range.

In fact, you can almost certainly just bisect from 89840966c579 to
bb5b583b5279, which is just 31 commits and should get you bisected in
just five tries or so.
