Something is wrong with my system and this error is showing up in syslog and kern.log at the rate of several thousand times per second. The fact that it's listed as corrected makes me think it's ephemeral and nothing is wrong, but the fact that it is showing up with such an obscene frequency filling up root is problematic (have you seen a 250+ GB kern.log?).

pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0018(Receiver ID)
pcieport 0000:00:03.0:   device [8086:2f08] error status/mask=00000001/00002000
pcieport 0000:00:03.0:    [ 0] Receiver Error         (First)
pcieport 0000:00:03.0: AER: Multiple Corrected error received: id=0018

Sometimes, there is another line saying can't find device of ID0018 thrown in the mix, too. Beyond these log entries filling up root, there are no other symptoms. The system behaves fine for what minimal browsing/video playing/encoding I do with it. Graphics outputs to the 4k display over HDMI with nvidia-343 drivers.

All I can really tell from that is the "device [8086:2f08]" is one of the root PCIe hubs off the CPU. The GPU is the only PCIe device I have plugged in, but I don't know if any of the on-board features on the motherboard may be off the PCIe bus, too.

Any suggestions as to what could be causing this, or any way to narrow down the options would be greatly appreciated. This is all the computer hardware I own, so swapping parts isn't an option.

you can determine the device attached to this root port with the command

lspci -v -s 3.0 | grep Bus:

you should see a line something like this:

Bus: primary=00, secondary=04, subordinate=04, sec-latency=0

the secondary and subordinate are often the same, so you could then use the command

lspci -s 4:0

to see what devices are on that bus. for my system here, it looks like this:

lspci -v -s 4:0            
04:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9123 PCIe SATA 6.0 Gb/s controller (rev 11)
04:00.1 IDE interface: Marvell Technology Group Ltd. 88SE912x IDE Controller (rev 11)

    I found the device using your instructions and it is "RTL8723BE PCIe Wireless Network Adapter". What to do now? – Jenny O'Reilly Apr 20 '16 at 17:25

    I've found the very same device: "RTL8723BE PCIe Wireless Network Adapter". What have you done then? – Baumann Jul 21 '16 at 20:22
  • Also for me it is Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter – user3405291 Jun 9 '18 at 6:25
