Thanks. With this LAPIC works better:
--- mp_machdep.c.prev2 2008-12-02 23:33:10.000000000 +0200
+++ mp_machdep.c 2008-12-02 23:26:23.000000000 +0200
@@ -1127,7 +1127,7 @@ cpususpend_handler(void)
atomic_set_int(&stopped_cpus, cpumask);
} else {
/* Set up local APIC again. */
- lapic_setup(1);
+ lapic_setup(0);
}
while (!(started_cpus & cpumask))
But statistic problem is still here:
# ps ax
