The sysctl is now kern.timecounter.hardware. For example: > sysctl kern.timecounter.hardware kern.timecounter.hardware: ACPI-safe If it is currently set to 'tsc', try changing it to 'i8254' and see if it works better. If so, you can stick that in /etc/sysctl.conf. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
