I am working on a custom system image and I got an aleatory kernel internal Oops error. The error occurs completely randomly, I can boot the board many times without presenting the error, but sometimes it appears just after booting while running udev. I will paste here my log information: The error is this:
[ 9.669062] Unable to handle kernel paging request at virtual address ffffffff
