Has this happened to you with equipment designed and manufactured the past 
5 years?

For me this was a problem with equipment released around 2000, since 
2005-2007 or so I haven't seen a single problem that I can recall.

I blame part of this problem on Cisco who was especially bad at handling 
autoneg. I remember in 1998 when we couldn't even get link up between a 
100 meg LE interface on a Sun and a (I believe) 3500XL. We had to use a 
hub in between to get link at all. Even worse, different port blocks on 
the 3500XL behaved differently.
