Hi,

I'm trying to run Linaro with kernel 4.14 in SMP mode on the Eragon 820 SOM, which has a Snapdragon 820: https://eragon.einfochips.com/ products/system-on-modules/qualcomm-snapdragon-820- apq8096-eragon-eic-q820-200-som.html

When running in SMP mode, the system crashes on a regular basis.

When compiling with maxcpus=1 nosmp, it works fine

if I remove CPUs 2 and 3 from arch/arm64/boot/dts/qcom/msm8996.dtsi , it will boot and show 2 CPUs and will work fine.

I wonder what I need to do to make it work (not crash) with all 4 cores?
