With the system idle, the load average always seems to be above 1:
rock@radxa-zero:~$ uname -a Linux radxa-zero 5.10.69-12-amlogic-g98700611d064 #amlogic SMP PREEMPT Tue Jun 14 12:47:53 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux rock@radxa-zero:~$ uptime 09:20:00 up 1 day, 2:00, 1 user, load average: 1.18, 1.17, 1.11
rock@radxa-zero:~$ sudo cat /sys/class/thermal/thermal_zone0/temp 36400
The system is connected to a WIFI network. I’m not using HDMI output or any USB peripherals – it’s powered by USB and that’s it. I have not made any changes to
/boot/uEnv.txt. I have installed
When I check with htop, I can see one core always at 20-30% utilization, but no processes with significant CPU usage (at the top is htop itself with ~2%).
Any tips on how to investigate what’s causing the above-1 load average? Thanks in advance!
