 I was setting up, or about to set up, two Dell 2950 servers with BCM5708 and 
 6.1 on them. Both servers survived "pkg_add -v -r cvsup-without-gui". Both 
 servers crashed within seconds on "pkg_add -v -r zsh".
 Both servers would crash within seconds trying to run cvsup. I also 
 experienced crashes during interactive shell work. I could however transfer 
 large amounts of data, seemingly without statistically making things worse.
 I do not have console access to them, so I cannot verify that I was seeing the 
 mbuf mapping error message, but I did verify through an at job that the 
 machine was definitely up and running even after network connectivity died.
 Both machines are now upgraded to 6.2 and so far the problem has not shown up. 
 Given old behavior I would have crashed them 50 times by now.
