    SubjectSOLVED: Re: (Random?) File System Corruption
    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. :)
