SOLVED: Re: (Random?) File System Corruption

["Joshua J. Kugler" <isd@as.uaf.edu>]

Well, don't I feel silly.  I some more investigating, and found that my 
problem didn't have anything to do with the kernel after all.  I, uh, found 
that I had a couple partitions over lapping.

Anyway, sorry to bother you all,  and now I'm going to go find some white 
powder to lessen the redness of my cheeks. :)
