Public bug reported: It would be nice to have a way to estimate memory in the kdump environment - not always the default crashkernel reservation fulfill users' requirements, specially in big servers with huge memory and multiple I/O devices.
Taking CPUs/RAM/devices into account and using early boot memory information + heuristic, it's possible to infer how much memory is going to be needed by kdump - see proposal [0]. This LP is to track the Debian progress of the issue and the future port to Ubuntu kdump packages.
