2.6.22 - Mission Impossible :-) -

Hi,

I continue with my effort to port last realtime-preempt patch available to
2.6.22.

If i compile without ACPI/hrtimers i don't have any problem (performance
and stability not tested yet).

If i compile with these i have a big problem:

---[ Cutted form kernel/timer.c ]---

void msleep(unsigned int msecs)
{
	unsigned long timeout = msecs_to_jiffies(msecs) + 1;
	while (timeout)
		timeout = schedule_timeout_uninterruptible(timeout);
}

------------------------------------

The while construct never return!

I think that Hrtimer subsystem isn't initialized when msleep called from
do_probe() (ide subsystem).

Someone have suggestions?

Thanks in advance!

Ciao,
Alessio
