At times it is just stops at this screen and doesn't move to the login screen. Or while it shuts down it stops at this screen.

This issue is related to the wifi adapter and 6th gen intel processors. Several new notebooks have reported such issue.

Use this link ( about the adding paramter to kernel here) to understand about adding kernel boot paramter temporarily and making it permanent. Then,

Add the parameter , pci=nomsi

And reboot.

If the problem is solved then make the change permanent. If does not work then try,

pci=noaer

same way and make it permanent if this works.

(*Reason for appearance is related to the recent Intel Skylake architecture CPUs and Realtek rtl8723be wireless adaptor.

The ubuntu team knows about it. Read more here Bug_track_ubuntu_PCIe bus error )
