> So.. What's going on? Am I the only one who notices these things? I have a feeling this only happens when the system load is high, not when the user load is high. And the funny thing is - my openoffice build (in this case) is running with nice -n 10, so even its priority is low. > Is this related to SCHED_ULE, should I try with SCHED_BSD? I thought the real strengths of SCHED_ULE only shows on SMP, am I wrong? I have been experiencing same symptoms you described on two of my SMP boxes, long time now. And I'm really going to get to the bottom of this, tried switching NIC's, audio cards, UP kernel, with and without ACPI.. I'll let you know when I come up with something useful. At least the symptoms surface a lot worse when all the -current kernel debugging options are turned on (=more system cpu load) Atte Peltomaki http://kameli.org
