Dear Beowulfers Did anybody ever get Gigabit Ethernet NICs to work on the Tyan Tiger S2466-4M motherboards under Linux?
If so, I would appreciate any words of wisdom about which NICs work, the appropriate BIOS settings, which PCI slots to use, etc. *** I flashed the Tyan S2466-4M BIOS to the latest version, V4.06 (super, final 2003 edition). I need to set this head node up with two GigE ports. I have two Intel 82543 Fiber Gigabit Ethernet PCI adapters, which use the e1000 driver. However, I would happily use other NICs and drivers, anything that works, including copper based GigE. *** I googled up to find tips and solutions, and I tried a number of different combinations: disabling the onboard 3Com Ethernet 100 port with a jumper; placing the NICs on the PCI-64 and on the PCI-32 slots; disabling the BIOS "option RAM scan" on the NICs' PCI slots; disabling USB on BIOS; trying one NIC at a time; etc. However, so far no game. The NICs are recognized, link LEDs light up, ping works, but the system seems to be unstable, ifdown/ifup hangs, hence the system hangs when it tries to take down the GigE ports during shutdown. Moreover, I get many of this kernel message on dmesg: Warning: kfree_skb on hard IRQ f88e47b2 *** This is the head node of our old Linux NetworX cluster. The original head node motherboard, ASUS A7M266, supported the aforementioned Intel NICs. Unfortunately it seems to have died. I bought an used-but-functional Tyan S2466-4M board on E-Bay as a replacement. These S2466-4M boards seem to have been very popular on servers and Beowulfs. It sounded to me as a good choice. After all, we have this board on all compute nodes. The compute nodes don't have GigE, only the onboard 3Com Ethernet 100 for service and I/O, plus Myrinet-2000 for MPI. They have been working fine for 8 years now. *** Thank you. Happy Holidays!
