We're using them on our new Opteron cluster that will start to blossom 
into a Barcelona cluster soon.

The biggest problem we've found is what appears to be a bug in the 
CentOS 5 kernel where the forcedeth driver does something bad to the 
IPMI module and locks you out until you next power cycle the system.

But as soon as we went to the mainline kernel (started at 2.6.22.3, 
currently at 2.6.23.1) those problems went away.

cheers,
Chris
