Just got a SuperMicro X8SIL-F board, and I'm having trouble getting the onboard Ethernet controllers to work. They are both Intel 82574L Gigabit. One of them has (rev ff) at the end in lspci.
Out of the box, both controllers show up as eth0 and eth1, but the connection on either is flaky and unreliable. I installed an updated driver from the Intel Download Center, but now I lost one of my controllers and only have eth0. They still both show up in lspci. I installed the driver by extracting the archive and running make install in the src folder, then restarting.
I'm running Ubuntu 10.04 amd64 64bit 2.6.32-24-generic.
Has anyone used this board with success?
