What's odd to me is that I get just fine throughput from/to hosts in our DMZ. The gateway is on the 10/100 segment. Things only get crappy when I try to talk to boxes (linux and windows) on the 10/100 segment.

The gigabit box is on a DLink 8 port switch, which connects to a 24 port Trendnet box. Everything was ok 'til I went to fc2 from RH8. Under RH8 I was using an older version of e1000 driver.

I'll try switching off autonegotiation. But I'm still stumpied.

Here's my output from mii-tool.
# /sbin/mii-tool -v
eth0: negotiated 100baseTx-FD flow-control, link ok
  product info: vendor 00:50:43, model 2 rev 3
  basic mode:   autonegotiation enabled
  basic status: autonegotiation complete, link ok
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
  link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

thx
