Hello, It was suggested to me that I forward this issue to you both. OS: 2.4.19.SuSE SMP Motherboard: Intel Dual P4 Xeon Server board SE7500CW2 (latest bios off Intel site) On-borad LAN controller: Intel 82557/8/9 [Ether Pro 100] (rev 0d) Addional NIC's tried: 3-COM 3C-905C-TX-M, Netgear FA311 dmesg output: e100: eth0: Intel(R) 8255x-based Ethernet Adapter Mem:0xfc221000 IRQ:7 Speed:0 Mbps Dx:N/A Failed to detect cable link Speed and duplex will be determined at time of connection Hardware receive checksums enabled cpu cycle saver enabled All three NIC's worked fine on 2.4.18.SuSE (SuSE 8.0) however I had to upgrade to correct non-functioning DMA on the on-board ide controller which now works. (The on-board Promise FastTrack100 RAID controller which also worked on 2.4.18.SuSE now fails with many "lost interrupts" messages...sigh) Trying to debug using mii-tool of mii-diag yields: SIOCGMIIPHY on eth0 failed: Operation not supported no MII interfaces found ifconfig eth0 shows all is fine however cannot ping the gateway with 2.4.19 as can with 2.4.18. I can ping its own ip address fine, Thanks in advance for any tips.
