Comment 21 for bug 1521173

I seem to have this issue too, but related to a different device. Running 16.04 with 4.4.0-31-generic. New (used) machine so very concering. It ran fine for about an hour then spontaneously started spewing this:

Jul 26 13:28:05 twin kernel: [ 8.837650] pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0018
Jul 26 13:28:05 twin kernel: [ 8.837665] pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0018(Receiver ID)
Jul 26 13:28:05 twin kernel: [ 8.837675] pcieport 0000:00:03.0: device [8086:d138] error status/mask=00000001/00002000
Jul 26 13:28:05 twin kernel: [ 8.837685] pcieport 0000:00:03.0: [ 0] Receiver Error (First)

lspci -nn gives me a match against this:

00:03.0 PCI bridge [0604]: Intel Corporation Core Processor PCI Express Root Port 1 [8086:d138] (rev 11)

and booting with pci=noaer suppresses the messages with no apparent ill effects.

But I don't know what the message is supposed to mean and I fear that I am suppressing a valid warning and gambling if I use the machine for serious work. Insights more than welcome. The machine is an ASUS G73Jh laptop Intel Core i7-720QM @ 1.60GHz / Nehalem 45nm). TIA.
