Thank you Dirk, I'll try that, If I update via apt-get shall I upgrade all the packages with "apt-get upgrade" or can I trust an "apt-get dist-upgrade" to work?
If I downloaded the new image I would have to connect via USB and wipe out the system and reinstall everything (pictory settings ...

Hi,

after some months of flawless activity, the ethernet connection of a RevPi Core 1 crashed, the attached DIO, DI modules kept working but the revpi was not reachable any more. Unplugging and plugging back the ethernet cable did not help, I had to switch it off and once back the ethernet was ...

Hi Mathias,

is there any news regarding the 0 reads of DIO modules and the modbus master connection loss upon reboot on Stretch?

Hi Mathias, Dirk,

I replaced the RevPi Core 3 with Stretch with one running Jessie and both issues have not shown up in the last four days, previously on Stretch I could spot 0 inputs every couple of hours.

Hi Mathias,

I updated the DIO module firmware to version 1.4 and the system has been running with no kernel errors for a week now. So thanks that fixed the instability for now, let's see what happens in the next month.

I guess this is why a downgrade to Jessie solved the problem for the other use ...
