I once worked at a place where we had BD 6808's at the core; one of them
consistently had hardware issues, and it took me the better part of a year
of fighting with Extreme to get them to replace the chassis, but when they
did, the problems went away, imagine that. I suppose similar isolated
incidents could happen with anyone occasionally though.
