This has been a problem with Intel x86 boxes starting with i8xx chipsets,
I have no idea why.

1/ network cards => brand and model ?
2/ network switches => brand and model ?

This seems to be the correct answer to the problem.

This is a SMP+Samba issue. Disabling HT on your P4 server will make it 
go away.
Disabing kernel oplocks in Samba is also a good workaround. I do not think
it is dangerous. This is not a RH/WB issue, as Debian had the same problem.

There is already a NTP client within 2K. Here is a how-to :
