I'm attempting to to install Ubuntu 18.04.2 in a desktop computer with a Windows. I downloaded it and made a bootable USB stick. I then chose the simplest install options and allocated 32 GB of my SSD. Ubuntu then loaded correctly, but, as soon as I rebooted it once, when trying to boot again, it just logs a lot of lines in a white font with a black screen behind. Those lines say:

pcieport 0000:00:1d.2: PCIe Bus Error: Security=Corrected, type=Physical Layer, (Receiver ID)

Reinstalling Ubuntu works again only once. As soon as I reboot it, I can't boot again.

  • Edit your question to include the output of grep AER /var/log/syslog* and sudo lspci -vt. Report back to @heynnema – heynnema Mar 21 '19 at 13:52
  • @heynnema I'm temporarily closing this question as I managed to fix it with a brand new install and following this before it started crashing. – MaiaVictor Mar 21 '19 at 14:37
  • That's where I was headed... but you should take off that kernel parameter... and run my commands... to see which device (0000:00:1d.2) is generating the errors... and then if there are AER errors in syslog... fix the cause, or use the pci=noaer parameter. – heynnema Mar 21 '19 at 15:14

Use the grep AER /var/log/syslog* and sudo lspci -vt to determine if you have AER errors, and which device (0000:00:1d.2) is causing them. Fix the cause, or use this...

sudo -H gedit /etc/default/grub # edit this file

Find:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

sudo update-grub # update GRUB

reboot # reboot the computer
