All my problems with watchdog timeouts and em 6.6.6 occurred when em
shared interrupt with USB but I don't know if it's MB, em or usb that's the
problem. Removing USB from the kernel or switching to polling and the
driver works just fine.

The fact that one of my test machines didn't have any problems was because
it had no USB in it's kernel. I had removed USB as I had problems with
watchdog timeouts with the bge driver when I first upgraded to the D915GAV
MB ages ago. The bge also shared interrupt with USB.
