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?
Thanks,
Jun
