I was getting these errors:
[ 1089.225561] pcieport 0000:00:1d.6: AER: Corrected error received: 0000:00:1d.6
[ 1089.225586] pcieport 0000:00:1d.6: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID)
[ 1089.225593] pcieport 0000:00:1d.6: device [8086:a336] error status/mask=00001000/00002000
[ 1089.225597] pcieport 0000:00:1d.6: [12] Timeout
Unfortunately these error are repeating too fast and avoiding other messages to be shown in the dmesg command.
The solution is easy, just add “pci=noaer” to GRUB_CMDLINE_LINUX_DEFAULT in the /etc/default/grub to include it on Linux kernel command line when grub boots Linux:
$ vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pci=noaer”
$ sudo update-grub
The reboot and the above message will disappear
