What is the problem?
Hi everyone,
I'm running Octopi with Octoprint on my RPi 4. I just changed my SD card with a new system installation. At first, all working fine, OS still boot up and seems working but I've seen some errors in dmesg (see last 3 lines in red on Putty). What are they meen ? What can I do?
What did you already try to solve it?
Don't know what can I do...
