[Linux-cluster] weird happenings on my cluster and another panic.

[isplist at logicore.net]

I missed the original on this but I had something interesting happen 
yesterday. I installed a new node, introduced it into the cluster and 
immediately, all of the other nodes died with a kernel panic. Not sure why 
yet.
