    can you run following scripts in first kernel?

    cd /sys/firmware/memmap
    for dir in * ; do
    start=$(cat $dir/start)
    end=$(cat $dir/end)
    type=$(cat $dir/type)
    printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type" >> /tmp/memmap.txt
    done

    and send out /tmp/memmap.txt

    what is your kexec tools version? could be too old?
