I am having troubles getting kdump/kexec functioning on an ARM dual-core ARM Cortex-A7 (a BMC by ASPEED AST2600) and QEMU. I do have kexec -l loading the new kernel, but after kexec -e the new kernel starts booting and the I get a watchdog BUG as shown here: [240.343350] kexec_core: Starting new kernel [241.639076] IRQ36: set affinity failed(-22). [241.657868] Bye! [ 0.000000] Booting Linux on physical CPU 0xf00 . . .

[swapper/0:1] [ 28.108383] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.10.14-47f127c #1 This is the first time I have worked on SMP section of the kernel. In order to get kexec to work I had to implement the SMP HOTPLUG; I suspect I do not have it functioning properly. I am not finding good information on implementing it. Is this something unique to each SoC based on an ARM dual-core ARM Cortex-A7? Looking for suggestions on how to successfully proceed. Thank you. -- Bruce Mitchell PS - Sorry this is a separate post from the one I did to linux-arm-kernel@xxxxxxxxxxxxxxxxxxx hadn't seen this email list at that point. _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
