Description of problem:
The following kernel panic has occurred two nights in a row. Exact message both times, different CPU. This was running on a brand new Dell Poweredge 1950. Two other identical servers, also new, running 2.6.9-67.0.7.ELsmp & 2.6.9-67.0.15.ELsmp have no issues.

The mgeDAE mentioned in the message is the UPS monitoring utility using SNMP to communicate with it. Same tool runs on other PE1950s with no issues.
