The patch below should address this problem for all architectures, by doing an explicit schedule() in the init code before calling into cpu_idle().

Yuck - wouldn't it be better just to fix all the architectures instead of applying band aid?


it's not really a bug in any architecture - it's a scheduler setup detail that i changed, and which i initially thought would be best handled in cpu_idle(), but which is easier to do in rest_init().


Hmm, what has changed is that secondary CPUs haven't got
need_resched set in their idle routines. Whether or not it
is possible to a task on their runqueue at that stage, I
didn't bother looking - I assume you did.

However, Ingo - instead of calling schedule() at the end of
rest_init(), why not just set need_resched instead?
