I've just had about the same problems and sent the machine back to the supplier, who contacted SuperMicro. Our machine had an Adaptec 39320 in it's PCI slot, in addition to the one on the motherboard. It seemed that the Adaptec in the PCI slot conflicted with the onboard network adapters. A Linux kernel (2.4.20 I believe) told me I indeed had a PCI conflict. FreeBSD 4.8 and 5.0 (both Current and RELEASE) didn't mention anything, but showed flaky network performance. The supplier exchanged the Adaptec 39230 with a half height PCI card (different PCI bus) and are running tests on the machine now. Zlo
