I am having these errors/warnings everytime I boot elementaryos with kernel 4.16 or kernel 4.17.2 on a ideapad 110-15isk with a i3 6006u and no dedicated graphics.
Does someone know how to fix them?
First two warnings are pretty harmless. (I have them almost a year now,on same v110-15isk like you). As for the rest,Im not sure. I do have Arch with 4.17 installed alongside eOS,and never saw such warnings.
It could be due to Ubuntu kernel-patches.
I wouldnt recommend running vanilla mainland kernel on any Ubuntu based distro.
If it means something,give HWE-edge kernel a shoot. It boosted performance and battery life for me.
