The clock is running too fast

Hola,

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

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.  :)

Hi folks,

AMD CUP
FreeBSD 5.2

The clock on KDE desktop is running on double speed compelling me to adjust
it
periodically.  Kindly advise how to fix this problem.

TIA
