Yes, the whine actually goes away under a full load. It is intermittent when the CPU is being stressed intermittently, and of course constant when the CPU is idle. I am going to try compiling a new kernel with a reduced HZ setting as suggested. Is the output of this command: sysctl kern.clockrate displaying the current HZ setting? If so it's 1000 at the moment. I will compile a new kernel using the GENERIC configuration file with only the HZ option changed to 100 rather then 1000 and report my findings. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-smp To unsubscribe, send any mail to "[email protected]"
