Rock64 radomly hang under high CPU load

[hasindu2008]

I am using the Linux build 0.7.9 with the kernel version 4.4.132-1075-rockchip-ayufan-ga83beded8524 on a rock64 board. When the CPU is under high load, the device randomly hangs and reboot after that. The system log contains messages such as the following at the time of hanging
(the full log at the time of hanging is attached at rock64_log.txt).

hrtimer: interrupt took 1458 ns
kernel: [175804.547254] Watchdog detected hard LOCKUP on cpu 3

The diagnostic log from rock64_diagnostics.sh -L is at

If any more information are required please let me know. Looking forward for a way to fix this issue.

Thanks
