A quick Google for 'Timecounter "TSC" frequency' led me to believe that I should change the hardware timecounter to i8254 with: sysctl -w kern.timecounter.hardware=3Di8254 I did that, rebooted, and ran sysctl -a again, only to see that kern.timecounter.hardware had reverted to TSC. I have both i8254 and TSC showing in dmesg. Should I make the change permanent across reboots, and if so, how? BTW, are any of you getting the same messages from this list over and over again? I am, I wonder what's going on? Thanks, Charles Got a computer with idle CPU time? Join SETI@home and help make history! http://setiathome.ssl.berkeley.edu/
