My kernel fails with kexec
Greetings, I have a kernel (which is not Linux kernel), and want to have it worked with kexec. That means I want to get kexec boot my kernel. Fortunately, kexec crashes when booting it. (with kexec -e command) My suspect is that my kernel is not written to "support" kexec. So could anybody tell me what is the requirement of a kernel, so it works with kexec? "kexec -e" spits out the below message in QEMU when booting my kernel. Any hint where the problem lies, and on how to debug the problem?

This was really wanted by laptop-carrying users, but I guess they'll have to wait for 2.6.23. Could you explain a bit: 1) Why CPU hotplug is that important for virtualization? 2) Why this patch is wanted by laptop users? I tried to answer myself those questions, but to no avail.
