Hi, I have tested kexec to Nuri board using Exynos4210(Dual-core ARM Cortex-A9) on the latest mainline kernel but i am facing one problem. The kernel enabled SMP, kernel_kexec() calls machine_shutdown to stop all cpus except current cpu and jumps to the new kernel but the kernel is hanged soon. I used cpu_down(1) to make disabled cpu1 instead of smp_send_stop of machine_shutdown and it is booted successfully to new kernel. Any ideas? Thanks.
