Oh, btw, can people who see this (Ying Han, Nick and apparently Jan) detail their configurations, please? In particular
- SMP? (CONFIG_SMP and how many cores do you have if so?)
- PREEMPT (NONE/VOLUNTARY or full preempt?)
- RCU (CLASSIC/TREE/PREEMPT?)
since those affect the kinds of races we can see a lot.
