Kernel bug--machine lockup

[jwantz at hpcc.noaa.gov]

Hi Janina,
No UPS just a surge protector sad to say.  I've had very limited 
electrical problems at my house in Howard County in the four years I've 
lived 
there.  We have some ancient transformers out front that are very 
noisy--they play havoc with the shortwave radio spectrum.  I've had no 
problems with power fluctuations unlike when I lived in Georgian Towers 
down in Silver Spring.
