I first tried this patch:

http://people.freebsd.org/~ariff/misc/idlecpu_apic_5.diff

which alone didn't fix the problem.

Then I changed machdep.c as described by Ariff:

## BEGIN ##
void
cpu_idle(void)
{

#ifdef SMP
if (mp_grab_cpu_hlt())
return;
#endif

if (cpu_idle_hlt) {
disable_intr();
if (sched_runnable())
enable_intr();
else if (PCPU_GET(cpuid) == 0) <<<<<
enable_intr(); <<<<<
else
(*cpu_idle_hook)();
}
}
## END ##

and inserted this in loader.conf:

machdep.cpu_idle_hlt=0

Now it seems to work :)

Thanks, guys!
Bye,

P.S.: Can this be merged into 6-stable soon?
