Hi Dan, Thanks for your advice. > I had a similar problem on one of the machines at work. Here is a memo I > made to myself to remind me of how to fix the problem in the future: > > The "ACPI-safe" Timecounter does not work (it is way, WAY too fast). To > get around this, add the following line to /etc/sysctl.conf: > > kern.timecounter.hardware=i8254 Added above line to /etc/sysctl.conf $ cat /etc/sysctl.conf vfs.usermount=1 kern.timecounter.hardware=i8254 Now only 2 lines in this file. I have adjusted the clock thereafter and will check it again later > There are multiple pieces of hardware capable of supplying timing > information to the OS. "dmesg | grep Timecounter" should give you a list > of all such devices. > > I think this is an ACPI-related problem, since that is the technology I > understand the least at the moment. $ dmesg | grep Timecounter Timecounter "i8254" frequency 1193182 Hz quality 0 Timecounter "ACPI-safe" frequency 3579545 Hz quality 1000 Timecounter "TSC" frequency 350797051 Hz quality 800 Timecounters tick every 10.000 msec Shall I run 'ntc' to synchronize the clock.
