No. In my case one is an Athlon64 and the other an Opteron.

In my case the controller is slightly different (29320), but I think the 
driver is the problem.
It used to work flawlessly as long as I run 5.x, but started freezing as 
soon as I upgraded to 6.1.
Notice, however, that I don't have data to support my thesis yet.
