PCIe errors "AER: Multiple Corrected error received: id=0040"

Hi Sir/Madam,

Since wifi module of TX2 is not stable enough, we add another wifi module with PCie interface on our custom board. We config USB lane mapping #4 and use PCIe#1_0(PEX2 Lane 3) to connect a wifi module with pcie interface.
Sometimes we can detect pcie chip by lspci but most of time we got errors as below repeatedly. Is it a hardware problem or kernel issue?

[   33.507441] pcieport 0000:00:02.0:   device [10de:10e6] error status/mask=00000001/00002000
[   33.507443] pcieport 0000:00:02.0:    [ 0] Receiver Error         (First)
[   33.597764] pcieport 0000:00:02.0: AER: Multiple Corrected error received: id=0040
[   33.597776] pcieport 0000:00:02.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0010(Receiver ID)

Thank you
Best Regards,

It’s a receive error of the PHY…this is almost always a signal quality issue.
