The support team at Linaro came up with the analysis and temporary solution for this issue on the RPB 16.06 release. Please read below:
The problem is with the missing 'hisi-acpu-cpufreq' module and the need to set the "power_allocator" as a thermal governor.
As temporary solution just add the following two lines to /etc/rc.local so it looks like follows:
test -f /etc/ssh/ssh_host_dsa_key || dpkg-reconfigure openssh-server
echo "power_allocator" > /sys/class/thermal/thermal_zone0/policy
in my tests I can see that the temperature does not rise above 75C.
