BananaPi M1 stops to work

Recommended Posts





my BananaPi M1 sometimes just stops working. The maximum uptime is 5 days. Usually the time is shorter. The system simply hangs. I can no longer access the system via SSH. When I connect a monitor to HDMI, nothing is displayed, so I can log in.

I have connected an external hard drive that is self-powered. I know the stories with the power supply. I have run ' stress -c 2 -m 1 '. The system remains stable.

I also executed 'armbianmonitor -u'.The log is here:


I checked syslog, daemon.log, user.log, armbian-ramlog.log for errors. With my amateurish understanding I did not find any error entries. In which logs can I still look up to search for errors?


I have installed armbian buster minimal. Additionally I have pihole, transmission (to seed armbian torrents and syncthing running. Other programs I have not installed yet.

There was no /etc/default/cpufrequtils in my case but /etc/default/cpufrequtils.dpkg-old instead. I've copied it to /etc/default/cpufrequtils, replaced 'ondemand' to 'performance' and rebooted a device.

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Uptime is 23 hours at the moment.

This tip saved me from buying a new bananapi m3. 

The second bananapi that was increasingly unstable : just stopped responding. In the past only once in a few weeks, nowadays every day. So unusable.

I had set it to email me every 5 minutes and it also stops doing that. 


Now I have set governor to performance and it's up for almost a day now. So seems good so far.


If anyone has an idea why this governor change works I would certainly like to understand it. Probably some cpu-state in rest that it can't come out of? There are no signs anywhere of a crash.
