Hello Cascardo, > > My understanding is that the kernel should handle that. Otherwise, whenever Sadly, it can't as kexec-tools is the one that creates elf headers for /proc/vmcore. So, with a change in available CPUs/memory, kdump kernel needs to be reloaded. Probably, with a udev event that does a try-restart of kdump-tool service on CPU/Memory hot add/remove operation. > the user manually loads a different kdump kernel, a memory hotplug would > cause the default kdump kernel to be loaded, not what the user has loaded. Can't do much about it. If need be, a user has the option to workaround this problem by adjusting the settings in /etc/default/kdump-tools file to load a different kdump kernel..
