<pre>4.15 had a number of things added to it.
One thing is using hugepages in ttm, which a lot of people have reported issues
with. Try disabling CONFIG_SWIOTLB (not really needed on modern hw, afaik).
Also nouveau's vm got a rewrite. Some fixes needed to be applied, I think
they're all in 4.16, not as sure about 4.15.x.

which doesn't look extremely familiar. "FIFO is confused", after which
everything goes downhill pretty fast.</pre>
