Rock Pi 4 SE file system not responding

Hello,

I have been having problems with the new version of Rock Pi 4 SE (v 1.53).

Before this version, I bought around 10 Rock Pi SE and they were working fine with the Ubuntu 20 Server OS downloaded from this site https://wiki.radxa.com/Rock4/downloads.

We bought a few months ago new SBC and this new version (v 1.53) came. I tried to flash the previous OS without success. Then I changed to the recommended one, Debian 11 and it boots up. Nevertheless, after a period of time, sometimes 1 day or sometimes a few hours or even less, the system freezes.

I must point out that it does not freeze completely (I have a python script running logging temperatures and it keeps doing it), but things like the Wi-Fi module and most of the system related processes are frozen. The message in the desktop says: “file system mounted at / is not responding”.

I also checked this site: https://github.com/radxa-build/rock-4se/releases and tried to install the headless Ubuntu rock-4se_ubuntu_jammy_cli_b38.img.xz. Same thing happens but I do not get the message as it is headless.

I am downloading the headless Debian OS to try it out, but I am already guessing I will get the same outcome. Has someone encountered this problem before?

I would gladly welcome some help with this.

Thank you so much!
