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?
