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. _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
