Hi all, my PI went bananas again last night. I did hook up a monitor to my PI and it did show error messages from 01:52 onwards.
I have added my findings to the github entry as the person involved there (Michael) suggested I do that.
In short the following error messages seem to be the interesting ones:
[#####.#####] mmc0: card never left busy state
[#####.#####] mmc0: error -110 whilst initialising SD card
Looking up these messages in google show remarks on bad SD cards.
But I am not entirely convinced here:
- The error only happens every sunday at around 02:00
- Rebooting any other time (hard or the proper way) does not cause this to happen
One remark did trigger a new line of thought though: it might be that my card is a fake 32GB.
The card tells the system it is indeed 32GB but in reality it is only 16GB.
At 02:00 the PI is doing some health check including the state of the SD card and tries to access the SD card beyond the 16GB and goes into error mode.
So, I am going to buy a new 32GB card and try to copy my HASS.IO setup to this new card and look what happens. If no error occurs then I will check the old card to see if my assumption is correct.
