I have an RPi 3 Model B V1.2 running Raspian Stretch.
Yesterday, since I hadn't done it in a while, I did an update and an upgrade procedure. A couple hours later I closed my work and did a normal shutdown sequence. The next morning on power-up and boot, I saw kernel failure messages followed by the normal graphical desktop screen but with non-functioning USB keyboard, USB mouse and no Wifi login.
Can anyone help me recover from this situation?
