| gem0:  glags8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500

| ether xx:xx:xx:xx:xx:xx
| inet 168.xx.xx.xx netmask 0xfffffc00 broadcast 168.xx.xx.xx
| media: Ethernet autoselect (10baseT/UTP)
| status:  active

Did you set the media type yourself? If it's the case, are you sure that
~ half-duplex on 10baseT is what you need?

Try setting the media type to auto
| ifconfig gem0 media auto

| Thanks.

Hope this helps,
