I press CTR + Alt +F1 or F2 on Ubuntu and the screen flashes repeatedly as follows:
PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e8(Receiver ID)
As the search on the Internet, I found only: https://blog.csdn.net/qimengxingyuan/article/details/80874314?utm_source=blogxgwz2
His id=00e5 is different from mine, but I can’t find it. Follow the instructions:
——————— 
Specific operation
Edit the grub
Sudo gedit – H/etc/default/grub
Add boot option
Find GRUB_CMDLINE_LINUX_DEFAULT = “quiet splash.” ”
Add behind pci = nomsi pci = noaer pcie_aspm = off
— — — — — — — — — — — — — — — — — — — — —
I am in GRUB_CMDLINE_LINUX_DEFAULT = “quiet splash” added after the concrete is:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” pci=nomsi pci=noaer pcie_aspm=off
I tried it and it still didn’t work, And I thought I made a mistake and I tried it a couple of times and it still didn’t work, and finally I saw this

Oh, I finally found it. It was my wrong way to modify it. The correct modification is as follows:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pci=nomsi pci=noaer pcie_aspm=off”
Then, as described in the two blogs above, perform:
1. Save the modification and exit
2, execute sudo update-grub
The 3, reboot
is now complete.
thanks for the above two detailed records
