Sorry for the delay in replying. I think this is it:


em0: link state changed to UP
em0: Excessive collisions = 0
em0: Symbol errors = 0
em0: Sequence errors = 0
em0: Defer count = 5622
em0: Missed Packets = 0
em0: Receive No Buffers = 0
em0: Receive length errors = 0
em0: Receive errors = 0
em0: Crc errors = 0
em0: Alignment errors = 0
em0: Carrier extension errors = 0
em0: XON Rcvd = 6209
em0: XON Xmtd = 0
em0: XOFF Rcvd = 21561
em0: XOFF Xmtd = 0
em0: Good Packets Rcvd = 1419602
em0: Good Packets Xmtd = 1631954

em0:tx_int_delay = 66, tx_abs_int_delay = 66
em0:rx_int_delay = 0, rx_abs_int_delay = 66
em0: fifo workaround = 0, fifo_reset = 0
em0: hw tdh = 0, hw tdt = 0
em0: Num Tx descriptors avail = 256
em0: Tx Descriptors not avail1 = 0
em0: Tx Descriptors not avail2 = 0
em0: Std mbuf failed = 0
em0: Std mbuf cluster failed = 0
em0: Driver dropped packets = 0

I am starting to become convinced that it is the motherboard though, I have 
tried the card in a Nforce3 (Asus A8n) and Nforce4 (Asus A8n-SLI) board and 
been unable to reproduce the problelm

Thanks.
