 >>Description:
 > The problem appears when using Intel PRO/1000 MT Dual Port Server Adapter=
  (separate card, not motherboard integrated) in dual-port mode.
 >
 > When I boot the system without ethernet connection or with only one port =
 plugged the driver starts as usual and works with no problem. But if I conn=
 ect both ports the driver gives this message:
 
 [...]
 
 > em1: Memory Access and/or Bus Master bits were not set!
 
 [...]
 
 Just stating the obvious, these messages look like they're a good
 start to look into the issue you're seeing.
 Thanks,
