If Supermicro boards are bug-ridden, then I'd expect other manufacturer's boards to be equally bad or worse. I don't have a reason to defend Supermicro or some such, but where else in retail do you get specialized server boards like Supermicro sells? When Opteron was relatively new in 2004, I bought a two-socket board from Supermicro as the alternatives from well-known Taiwan manufacturers (ASUS, MSI, etc.) weren't as sophisticated (hadn't the PSUs and PSU connectors, power ratings, and rack-mount/tower convertible enclosures).
