Trying nouveau reclocking

The warn in question is
static u32
nvkm_mc_intr_mask(struct nvkm_mc *mc)
{
u32 intr = mc->func->intr_mask(mc);
if (WARN_ON_ONCE(intr == 0xffffffff))
intr = 0; /* likely fallen off the bus */
return intr;
}
Which is basically a sign of total death. Is this new with 4.5-rc1, or
is this the first time you've tried reclocking this chip?
