What does the bootlog say?

I tried x15 on next. I see

BUG: using smp_processor_id() in preemptible [00000000] code: swapper/0/1

and

WARNING: possible circular locking dependency detected

But I don't think those affect DSS.

I see cma allocs failing for many drivers:

cma: cma_alloc: alloc failed, req-size: 1 pages, ret: -16

Which obviously breaks dss...
