I recently noticed that the system clock on a machine i recently set up is running very quickly, about 2x realtime by my measuring. What can i do to solve/investigate this problem? What information would be helpful?
Try changing the kern.timecounter.hardware sysctl; you can look at the available choices via:
sysctl kern.timecounter.choice
Thanks for all the advice everyone. The solution was changing the kern.timecounter.hardware sysctl to i8254 (was ACPI-safe). I was using NTP, but when the clock is at 2x even having cron run ntp every minute is too innacurate.
Thx again! Ryan
I wish I'd known about that sysctl when I had this problem on my last system! I tried ntp, but having ntp constantly resetting the clock just added new problems.
Thanks for sharing the outcome with us.
