Hey,
I had a deeper lock into the problem using ftrace. Below I attached a few of the traces which are showing the failing I2C transfer (only).
I2CNormalTrace_I2CEventsOnly - Shows a trace of only the I2C events when the I2C transfers is performed successful.
I2CStuckTrace_I2CEventsOnly - Shows a trace of only the I2C events when the I2C transfers is failing. A long delay between I2C write transfer and result can be observed and the return value is Errno 121 - Remote I/O Error.
My assumption is that something is interrupting or blocking the I2C transfer. To find out what this could be I enabled other trace events in the hope that the culprit leaves some hints. I separated all available trace events into 4 different sets and activated only one set of events each time in order to keep the trace readable. The trace of the first event set did not show any logs between the I2C write and the result of the failed transfer. The traces of the other three event sets showed many logs in between the I2C write and the result. I have attached the three traces below (I2CStuckTrace_EventSet[1-3]). Unfortunately I am not able to distinguish if a log is fine or a potential problem for the I2C transfer. Maybe someone with some more experience can have a look on the traces and help? I would really appreciate that.
Thank you!
