Hi Dave and Kairui, thanks for your responses! OK, if that makes sense to you I'm fine with it. I'd just recommend to test recent kernels in multiple distros with the minimum "range" to see if 64M is enough for crashkernel, maybe we'd need to bump that.

Giving the different kernel configs and the different userspace initramfs setup it is hard to get an uniform value for all distributions, but we can have an interface/kconfig-option for them to provide a value like this patch is doing. And it could be improved like Kairui said about some known kernel added extra values later, probably some more improvements if doable.

Thanks Dave
