In my case, the problem was because the PHY was advertising and connecting full-duplex and the CPM was doing half-duplex -- yet another problem due to inadequate PHY communication. Also, there is a problem with the 8260 CPM generating spurious TX underrun errors and late collisions -- the driver does things according to the spec, but there is an errata about this problem. I'm about halfway through a fix for this. The problem only seems to occur on 10 Mbit hubs. dave... ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
