 of course fixes the issue immediately...) .

 I can now confirm that a similar copy to the vr card does not cause
 the same problem... so it would appear
 more likely that it might be an em related problem.

and after replacing the em0 with a realtek gigabit card, the problem
also does not occur. (the vr0 was only 100mb)
So it would seem there is something hinky with at least the em (82540) card .
