OrangePI 3 ubuntu server kernel 4.9 only one CPU core

Hi,
I installed the latest image OrangePi_3_Linux_4.9_Ubuntu16.04_Server_emmc_v1.0.tar.gz but i have only one core working, others are offline.
root@OrangePi:~# lscpu
Architecture:          aarch64
Byte Order:            Little Endian
CPU(s):                4
On-line CPU(s) list:   0
Off-line CPU(s) list:1-3
Thread(s) per core:    1
Core(s) per socket:    1
Socket(s):             1
CPU max MHz:         1488.0000
CPU min MHz:         480.0000

I tried to enable them withecho 1 > /sys/devices/system/cpu/cpu1/online but they still are off line.

What's wrong ?

i would say 4.9 is more testing release. looks like cpu is thinking that it is overheating and preventing 1.8 ghz clock plus removing cores, but if you put some load i guess they should appear. if you do not need hdmi then armbian latest release with kernel 5 version is better chaise there

Hi,
I don't use the hdmi output, my pi is a headless server.
Actually Armbian isn't listed for Orange PI 3 http://www.orangepi.org/downloadresources/

It's not there to limit wasting our human interaction support resources ... but you can build an image, which might just work. "Might" is there because it is still under development.
