[1.] One line summary of the problem:
PCI bus error on startup while booting into login screen (Kubuntu 16.04)

[2.] Full description of the problem/report:
With a HP Pavilion Notebook - 15-ab549tx, and Kubuntu 16.04, the
problem is on startup error messages show up before the login screen
as per attached
screenshot:https://launchpadlibrarian.net/263296837/screenshot.jpg 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. WORKAROUND:
Adding kernel boot parameters: pci=nomsi pci=noaer stop the messages
from showing on startup, but it takes 2.5 minutes to boot.
