I have a new HP Pavilion Gaming Notebook and a new installation of Ubuntu 16.04. When I press Ctrl + Alt + F1 I go start seeing the errors shown in the following image and it doesn't allow me to interact with the console:

enter image description here

I also see these errors for a while everytime I boot. I need to do Ctrl + Alt + F1 to access a non graphical terminal to install some Nvidia drivers. What's going on?

What's causing the problem seems to be: 00:1c.5 PCI bridge [0604]: Intel Corporation Sunrise Point-H PCI Express Root Port #6 [8086:a115] (rev f1)

    Could you post the output of : ` lspci -nn ` . Thanks – ankit7540 May 13 '16 at 16:22
  • @ankit7540 I've updated my question with that info – João Abrantes May 13 '16 at 17:25
  • Hey been a long time, same issue with same notebook did you solved it now? – Vinz243 Aug 8 '16 at 15:10
  • Yes @Vinz243 the answer bellow solved my problem after all! – João Abrantes Jan 22 '17 at 12:51
  • I'm getting this also on Ubuntu 18.04, so this is the bug that keeps giving. – Kingsley Oct 14 '18 at 21:21

Try this,

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 )

  • Did you try this, pci=noaer ? – ankit7540 May 14 '16 at 10:44

    I had the same problem. Both your solutions worked. I went with pci=noaer as this is the first one mentioned in the ubuntu team link you posted. Thanks. – user643722 Nov 18 '16 at 9:46
  • to make it permanent, use askubuntu.com/questions/271058/… *note that there are two similar lines to modify – Ferroao Jun 30 '17 at 18:52
  • I'm using an HP Pavilion 15-ab217ng notebook with Ubuntu 16.04. I had these errors for years and they were driving me nuts. pci=noaer worked for me. Thank you so much. – Jenny O'Reilly Dec 6 '17 at 17:47
  • pci=noaer help me on Xubuntu 14.04 – Luis Lasser Feb 8 '18 at 16:18

Here already answers are provided which also helped me a lot. I use text mode of ubuntu 16.04 and so

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

didn't helped me. Here what I changed was -- (in /etc/default/grub)

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
GRUB_CMDLINE_LINUX="text pci=nomsi"

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

which solved my error(NOTE - I used only pci=nomsi, and in case it don't work other option is pci=noaer), that may help solve anyone facing the same error.
