While the offset is changed to 128MB in some releases, it is still 32M on some.
Having the default crashkernel offset as 32MB is NOT a good idea. It would leave
the production kernel un-bootable. Please drop the offset of 32M/128M and
let the kernel decide on the offset in default case to ensure we don't end up
in a scenario where production kernel is unbootable. This applies to all
Canonical releases..

Thanks
