My experience is that the bge driver works better for some  broadcom  
chips than others.  I have one box on which it is totally worthless,  
contributing to file system lockups of all things (a Dell PE800), and  
others on which it is pretty stable and fast (e.g., Dell PE SC1425,  
PE SC430).

On our PE800, I had to disable the bge on BIOS and plug in an em- 
based NIC card.  Made a world of difference in system stability and  
performance -- it is actually usable now :-)

All boxes run FreeBSD 6.1 except the PE800 which runs 6.2.
