Kexec another kernel B (crash dump enabled) in kernel A. >From a short glance over current Linus' arch/i386/kernel/machine_kexec.c, memory for the crash dump kernel B still needs to be reserved statically when booting A. This is one of the biggest issues with kexec based hibernation. For the typical notebook user, it is totally unacceptable to reserve 16 megabytes of memory just to be able to suspend to disk. And given the fact that current distribution kernels are quite modular and require early module loading, even more memory might be needed. IMHO, a plan how to fix this must exist or the concept of kexec based hibernation is a waste of time.
