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..
