Server Hardware for openplotter?

Hi,
so if I understand it right, you use the moitessier hat?
There are errors in your Log:
[   14.717200] moitessier_processReqData - HEADER_payloadIsValid(...) failed
[   14.760517] moitessier_processReqData - HEADER_payloadIsValid(...) failed

I cannot reproduce this issue but think there is something wrong with your moitessier HAT. ( I did not have a moitessier HAT)
Can you check without the Hat.
Can I take a look at your System with AD after this?

Yes, I have the HAT and until kernel 5.4.52 everything was perfectly fine.  With 5.4.79 to which the HAT has also been updated, the error on the ttysc serial has been released.  It's ok if you can check with AD yourself, but you need to tell me how to do the remote connection.  Then I don't speak English, I write through Google translate.  This afternoon after 17 Italian time I would be there.
