I did also test 4.9-rc5 and it behaves like all the rest (since 4.8). My problem is gone when CONFIG_SMP is set.
That doesn't mean that there are no extra bugs here, dependant on the presence or absence of other options.

I experience a sliding scale. With debug it crashes immediately. It may crash later on (even at shutdown time). It's not even an oops but a warning. In the end it happens to just work.
