>Description:
the time of day clock runs fast.  For example:

$ date; sleep 5; date
Fri Nov 23 14:12:55 GMT 2001
Fri Nov 23 14:13:05 GMT 2001

$ sysctl kern.timecounter.hardware=TSC
$ date; sleep 5; date
Fri Nov 23 14:13:17 GMT 2001
Fri Nov 23 14:13:22 GMT 2001

In both cases, the subjective time was 5 seconds.

Here is a dmesg output.

 I'm fairly sure this is due to broken hardware for the ACPI timer.
 Atleast I had the same problem with one machine running -current
 and resorted to using the TSC as a timecounter again too.
 
 I don't know if it is a common enought problem that there should
 be a work around. It may well be worth it to avoid a deluge of
 complaints when -current becomes -stable. (Mind you, people with
 broken ACPI stuff will have enough problems when -current becomes
 -stable anyway.)

 I get this problem on my system board as well.
 I've pasted the relevant dmesg output
 
 I can also note that this problem is still prevalent in the kernel as of
 FreeBSD 5.0-CURRENT-20030209-JPSNAP

 FYI, I'm having the same problem on an ASUS P5A, BIOS 1011 BETA,
 K6-2 500Mhz.
 
 Setting kern.timecounter.hardware to TSC seems to have solved the problem.
 
 Cheers,

 One more thing:
 
 I'm running 5.1R.  The problem did not occur under 4.6R, 4.3R, or 3.2R
 on the same machine.  Don't know if it matters, but I did upgrade the BIOS
 from 1007 ro 1011-BETA at the same time I upgraded to 5.1R.  ( Had to to get
 my 80 gig IDE drive recognized )
