Is this accidentally the port that shares a PCI IRQ, i.e. (old system, not 2.4 kernel) $ dmesg|grep ^eth|grep -i irq eth0: Digital DS21140 Tulip rev 34 at 0xd000, 00:C0:95:E0:31:28, IRQ 5. eth1: Digital DS21140 Tulip rev 34 at 0xd400, 00:C0:95:E0:31:29, IRQ 10. eth2: Digital DS21140 Tulip rev 34 at 0xd800, 00:C0:95:E0:31:2A, IRQ 15. eth3: Digital DS21140 Tulip rev 34 at 0xdc00, 00:C0:95:E0:31:2B, IRQ 11. eth4: NetGear GA620 Gigabit Ethernet at 0xe4410000, irq 11 So, IRQ 11 is assigned to both eth3 and eth4. I have noticed that pumping lots of traffic this path in a non-bridged setup can result in really bad performance compared to using another port on the 4xTulip card. -andreas -- Andreas Ott [EMAIL PROTECTED] Network Architect @Home Network http://www.excitehome.net/ Excite@Home 450 Broadway Street Redwood City, CA 94063-3132 USA phone +1 (650) 556-5460 fax +1 (650) 569-5856 pager +1 (650) 524-8073 _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
