I am on 5.1.5 Hera, latest everything, XPS 9550 latest BIOS and I would like to know what are those errors in my dmesg

The only thing I did was installing the latest Nvidia drivers via AppCenter (440.59) and install BB Switch, to properly turn off my Nvidia card when not needed and save battery (99% of the time).

Thank you very much
