hello can i get an opinion on how to fix this kernel error ? it happened after i tried to install mainline kernel 4.7 from ubuntu but it didn't have the necessary patches for 16.04 lts and i'm not confident to do that myself. i went back to the latest stock kernel of the day from ubuntu repo but have this pastebin error http://pastebin.ca/3669156 from kernel boot. thanks.

The issue appears to be minor, and should not hinder your system use. However, I am seeing a possible issue with your network manager. Does your system boot? If so, do you have internet access?
