[ale] multi-processor vs. Tape Drive

Wed May 25 11:59:28 EDT 2005

I've tried using diff to compare the config files, but none of the differences jump out at me as a potential cause (although this may be where my limited kernel knowledge may be hurting me).

"diff" the two .config files to see what is different.
