Subject: sis900 tx timeouts

I have an Intel motherboard with an sis900 nic chipset down on the
board.  When i put the NIC under heavy send traffic i start to see
Transmit error's in dmesg and the nic stops sending data.  if i do an
ifdown eth0; ifup eth0 the nic starts responding again just fine and
will run for a while, but eventually the transmit errors return.  Can
anyone lend advice on how i might fix or help track down this error?

thanks
