i5Js Posted May 24, 2020 Posted May 24, 2020 Hello all, I have this board and It's suffering crashes and reboots all day. I think the logs are stored in RAM because I can't never find anything related to this issue. Is there anything I can do to find the cause? Many thanks. Regards.
Werner Posted May 24, 2020 Posted May 24, 2020 Frist things first: armbianmonitor -u Quote I think the logs are stored in RAM That is correct. From the documentation: Quote /var/log is mounted as compressed device (zram, lzo), log2ram service saves logs to disk daily and on shutdown This has two reasons: First it increases the lifetime of your sd card significantly because it avoids tons of small writes to it and 2nd writeing to zram is way faster than writing to sd card.

i5Js Posted May 24, 2020 Author Posted May 24, 2020 Thanks both for your replies. Armbianmonitor output has been uploaded to http://ix.io/2ndb It's booting from emmc memory
Werner Posted May 24, 2020 Posted May 24, 2020 Quote "python3" (3688) uses deprecated CP15 Barrier instruction at 0xf6f30694 Just found via google. You can disable this "spam" with echo 2 >/proc/sys/abi/cp15_barrier About your actual issue, sorry no idea

balbes150 Posted May 24, 2020 Posted May 24, 2020 Sorry, I don't use the 4.4 kernel, I don't know what bugs are in it now. I don't have any problems on the 5.7 core (the system is on eMMC and NVMe).
i5Js Posted May 24, 2020 Author Posted May 24, 2020 And what about the fan control? Because I've downgraded to 4.4 because of that.

The fan is controlled automatically. I use T4 to build images of LE and ArmbianTV (this is the maximum load on the entire system) and the fan works correctly (when need to turn on the minimum speed, and when continue to increase the load goes to the maximum speed of rotation).
i5Js Posted May 28, 2020 Author Posted May 28, 2020 Yesterday I reinstalled on kernel 5.4.32 and it's working fine, just 24h without any reboot. The fan works fine and the temperature is stable around 50 degrees. Fingers cross!
