--- Comment #7 from Ilia Mirkin imirkin@alum.mit.edu --- Interesting. Dies in PMU preinit somewhere, which in turn calls nkvm_pmu_reset. I don't see an obvious reason for that to die except ... if PTIMER is somehow off?
The only difference is from 1e2115d8c0c0da62405400316f5499d909e479bc which makes it so that nvkm_falcon_v1_new is now being called, although I can't imagine what would go wrong there.
This will require someone who knows what they're doing to figure out ... i.e. not me. Hopefully Ben can take a look.
