Problem with bz-8 scyld

[Art Edwards]

We had successfully built bz-8 and run parallel jobs. However, the head
node was unstable, hanging every few hours. So we went to the scyld
site, downloaded and installed all of the updates. Now, the head node is
up, but none of the slave nodes will boot completely. They hang in phase
3 with the startup of bpslave daemon.

Any insight would be very helpful.
