Found it. Ubuntu had ethtool so I was able to: sudo ethtool -s eth0 speed 100 duplex half autoneg off
and, volia.. that did the trick. Why I did this might interest someone out there so here it goes. We have a Cisco 3550 set to 100/full on every 100 meg port. No autoneg, no nothing. We have a UNIX server (sun starfire 240 in this case) when it reboots the amber light on the switch goes nuts indicating collision (impossible in full-duplex mode) and the switch port racks up a ton of CRC errors but not collisions. This is to be exepected as the switch doesn't expect collisions so it racks up the jam as CRC packets. Once the port is unplugged the server reverts back to 100/full as it should (as it is set up in the config) and everything is normal until the next reboot. Strange. I don't know why the server does this. Wake on LAN maybe? I don't know but it appears that once the server goes down the card comes alive with it's own settings of some kind that aren't reset by the config on the server itself. Very strange.

Is that Sun hardware, or maybe some vendor's, like Broadcom? Does lspci tell you? Peace.
