Timekeeping in stable/9

[Joe Holden]

Hi guys,

Has anyone else noticed the tendency for 9.0-R to be unable to 
accurately keep time?  I've got a couple of machines that have been 
upgraded from 8.2 that are struggling, in particular a Virtual box guest 
that was fine on 8.2, but now that's its been upgraded to 9.0 counts at 
anything from 2 to 20 seconds per 5 second sample, the result is similar 
with HPET, ACPI-fast and TSC.

I also have physical boxes which new seem to drift quite substantially, 
ntpd cannot keep up and as these boxes need to be able to report the 
time relatively accurately, it is causing problems with log times and 
such...

Any suggestions most welcome!

Thanks,
J
