Hi, I've just checked and it seems a bit weird, at least not as I expected: the workqueue is already initialized _before_ cpufreq! At least, from what I read in init/main.c, in do_basic_setup(), first there is a call to init_workqueues(), then there is a call to do_initcalls() (which indirectly calls cpufreq_core_init()). So maybe workqueues need something more than being initialized to work? What could it be? (My kernel is compiled for monoprocessor, I can't see what goes wrong in wq_per_cpu()).
See you, Eric
