Why does your virtual machine use a drm driver? Ah, it's a driver for
virtual gpu, nice.
And if you revert that patch, does everything work again?

You should also cc: the other developers on that signed-off-by list,
like I did here...

Great, Dave, care to revert this in 4.18 so I can queue up that revert
in older kernels as well?

Hi MIke,
Does
https://patchwork.freedesktop.org/patch/229980/
fix it?
I can queue up a revert asap, but since a revert just brings us back
another broken behaviour, I'd rather we just hurry the fix up.
Dave.
