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 From mboxrd@z Thu Jan 1 00:00:00 1970 From: jy0922.shim@samsung.com (Joonyoung Shim) Date: Wed, 11 Jan 2012 17:45:47 +0900 Subject: ARM kexec SMP problem using exynos4210 Message-ID: <4F0D4C3B.80208@samsung.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
