Public bug reported: A fresh install of Ubuntu Server 18.04.1. It keeps printing the same messages to the terminal:
[ 1475.344317] pci 0000:00:00.0: aer_status: 0x00000080, aer_mask: 0x00000000 [ 1475.345586] pci 0000:00:00.0: aer_layer=Data Link Layer, aer_agent=Receiver ID The same two lines, over and over (except number in brackets), every 10 minutes or so. After logging in it still keeps printing them. The interval is not constant, sometimes longer, sometimes shorter. Performed apt-get update and dist-upgrade, rebooted. Now 0 packages pending update, but the above output is not affected. Googled to find that AER is supposed to report PCIe errors. However the above output does not look like an error. Seems like some log output? Naturally this randomly appearing output is extremely annoying and interferes with the normal use of the console. My guess is that a normally functioning install should have nothing of this sort, hence this bug-report. Any fix or workaround that will silence this output will be appreciated greatly. Let me know if any additional information or tests are needed.
