Hi, did anyone already happen to look into enabling CPU hotplug for the Allwinner A20 in upstream? I'm currently running the sunxi-next branch on Banana Pi, and echo 0 > .../cpu1/online just hangs the system. The old 3.4 LeMaker kernel works fine in this regard. I can try to look into details and port things over, just want to avoid duplicate efforts.
Thanks, Jan
