I have fresh install on Raspberry Pi 3 (with device tree switched off), but the module doesn't work and show in log

What can be wrong? What should I check?

Have you disabled Bluetooth? That had to be done on the Pi 3. I'm still having issues on mine though.

As I know new installer disables bluetooth, but of course I also disable it.

I am getting the exact same error log but I'm using a Raspberry pi 2. Figure anything new out?

So in the short time I have been playing with this I went into the Raspberry Pi Configuration and turned off serial under interfaces and that has seemed to fix it for me. Might want to try it on yours as well.

@BaneofSerenity:

That absolutely solved my problem! Stupid question maybe, but what made you even think to check that? I'm new to the Raspberry Pi and I don't know that I would have thought to turn off that specific interface. It makes sense now that I did though!

I have the same problem on my pi 3....

I did what you say and go to --> sudo raspi-config --> Advanced options --> serial --> disable

After do this i reboot the pi3 and I am getting the exact same error.
