Subject: Re: threadirqs and kthreadd_task

thanks Mike for info.
I add mips list in CC now.

In general, the problem does not look like arch specific. Arch code is
calling setup_irq. This code calls generic  __setup_irq. And then
threads are created by this line in kernel/irq/manage.c:
t = kthread_create(irq_thread, new, "irq/%d-%s", irq,
                                   new->name);

and kthreadd_task is uninitialized till this point.

The code looks similar for x86_64 so i am missing something obvious.

Nevertheless, I am hoping someone from mips-list can throw some light
if this feature works well on mips.

Thanks
