current we have:
1. crashkernel=XM
2. crashkernel=XM crashkernel_low=YM

so you want to change to
1. crashkernel=XM,low or crashkernel=XM
2. crashkernel=XM,high
3. crashkernel=XM,high crashkernel=YM,low

looks like you change your mind, now you are agreeing on
some could low and some could be high.
