Hmm. 3.19 works fine, even if it ends up spewing

    WARNING: CPU: 0 PID: 6 at drivers/gpu/drm/drm_irq.c:1121
drm_wait_one_vblank+0x125/0x130()
    vblank not available on crtc 1, ret=-22

a lot. But it doesn't have the problems I saw with current -git.

So it's new to this merge window.

I'll see how painful it is to bisect it,
