I've been following this on the Dell list as I have approx. 50 R410s  
in our cluster.

One thing that isn't clear--  When this happens, do you lose all 
connectivity to the node (i.e., do you have to reboot the node to 
re-establish eth0)?

My R410s are running CentOS 5.2 - 5.4 and I rarely have one go 
down.
