Hmmm... i had truss running but the moment it died it was running gettimeoftheday() so 
i am not sure :-/

I tried different ports on the switch.. It's a cisco switch btw, and other freebsd 
boxes on that switch
are not exhibiting similar problem....

I'll try putting this behind a hub or something other than cisco just for kicks but if 
anyone has any further ideas/suggestions, i'd really appreciate it.

Thank you!
