Is this one going to be be my fault too? [???38.947305] SMP: stopping secondary CPUs [???38.951291] Starting crashdump kernel... [???38.955207] ------------[ cut here ]------------ [???38.959818] WARNING: CPU: 0 PID: 312 at arch/arm64/kernel/machine_kexec.c:169 machine_kexec+0x220/0x298 That's the cpus_are_stuck_in_kernel() || num_online_cpus() one. Again, v32 applied to a 4.9 kernel. With the stray __init removed this time ;) Taking secondary CPUs down for a normal kexec does work via PSCI. I'll see if I can enable enough hardware support to let me test a newer kernel... -------------- next part -------------- A non-text attachment was scrubbed...
