Hi all, Looks like the reboot issue was caused by a memory hole not being reserved. It's defined in the downstream kernel source (link : [1]). Adding it makes the kernel boot fine (tested when booted from lk2nd) I'll try to send a patch with it tomorrow. Kind regards, Dominik [1] https://github.com/android-linux-stable/bullhead/blob/android-msm-bullhead-3.10/arch/arm64/boot/dts/lge/msm8992-bullhead.dtsi#L144
