When we run LS1046A custom board for long time, we see random errors. Mostly seen during overnight run. There is no impact on the performance. 

pcieport 0002:00:00.0: AER: Multiple Corrected error received: id=0000
pcieport 0002:00:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0000(Receiver ID)
pcieport 0002:00:00.0: device [1957:81c1] error status/mask=00000001/00006000
pcieport 0002:00:00.0: [ 0] Receiver Error (First)


Would be helpful if someone can point if these AER errors can be related to Signal Integrity or Electrical Margins on the PCIe  Interface.

Thank you
