Another way would be to
reorganise the initialisation code so that workqueue is initialised
before the cpufreq framework is started, do you think it's possible?
Making all this work with low-level drivers built in would be perfect of
course...
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
