Right now, except from the stuff Luis had broken and fixed, the real problem is that there are a bunch of bugs that appear to have been in the code forever, just never noticed -- for instance the code can end up calling synchronize_rcu() in an atomic section. This is the reason for disabling it -- it can splatter all over the scheduler if that happens, and it's not clear to me that it cannot happen. It seems not to happen in _most_ scenarios, but I've certainly caused it to happen by not beaconing, for instance. johannes
