Realtek rtl8188ee wifi card causes PCIe advanced error reporting to steal CPU and fill up disk

[Robert Sharp]

Hi,

Since installing a Realtek RTL8188EE based wifi card (TP-Link TL-WN781ND v3) PCIe advanced error reporting spams my logs with the errors shown below; these take almost all the CPU time of the machine and rapidly fill up the kern.log on disk (Many GBs every hour):

Dec 2 19:09:01 robert-System-Product-Name kernel: [ 9.452912] pcieport 0000:00:1c.6: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
Dec 2 19:09:01 robert-System-Product-Name kernel: [ 9.452913] pcieport 0000:00:1c.6: device [8086:a33e] error status/mask=00000001/00002000
Dec 2 19:09:01 robert-System-Product-Name kernel: [ 9.452913] pcieport 0000:00:1c.6: [ 0] Receiver Error (First)

I've confirmed that the device connected to that pcie port is the Realtek card:

To suppress the errors I've set pci=noaer in my kernel parameters, but I've been unable to determine root cause. I thought it might be related to ASPM, but my BIOS configuration has ASPM disabled and my kernel log shows:

Dec 2 18:59:09 robert-System-Product-Name kernel: [ 0.040769] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
Dec 2 18:59:09 robert-System-Product-Name kernel: [ 0.153587] acpi PNP0A08:00: FADT indicates ASPM is unsupported, using BIOS configuration

I'm running Ubuntu 18.10 with Kernel:
Linux version 4.18.0-11-generic (buildd@lcy01-amd64-027) (gcc version 8.2.0 (Ubuntu 8.2.0-7ubuntu1)) #12-Ubuntu SMP Tue Oct 23 19:22:37 UTC 2018

If it helps, lspci -vvv of the Realtek card is below:
