    It will usually only say there is no core dump if the kernel binary
    doesn't match the saved core or if it is checking for the core in the
    wrong place.

    When it happens again, try using 'savecore -f /var/crash' after
    rebooting to try to force it to generate a core.  If you are booting
    from a different kernel binary then /kernel, use the -N option (do a
    man savecore) to specify the location of the kernel binary.
