Yep, i really suspected it was something with the 3com card. Found
something on the bridge FAQ regarding 3com cards (setting
interrupt_work=10000). If you have additional options such as indicated
on the bridge FAQ available that you know or links that discuss this
please let me know.

would you know of any network card that can work as a bridge and at the
same time has NAPI drivers?
