An MCE is an error reported by the hardware. It is most likely not a software problem, not much kernel people can do about it. Google for "parsemce.c" to find a program that'll decode most MCE's for you. You may also want to contact your hardware vendor to get an exact explanation for the error. -- Jesper Juhl <[EMAIL PROTECTED]> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
