Hi,
Working with a sample for a new laptop based on Intel Skylake, the kernel logs are full of these messages:
pcieport 0000:00:1c.5: AER: Corrected error received: id=00e5 pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID) pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 pcieport 0000:00:1c.5: [ 0] Receiver Error (First) pcieport 0000:00:1c.5: AER: Corrected error received: id=00e5 pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID) pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 pcieport 0000:00:1c.5: [ 0] Receiver Error (First) pcieport 0000:00:1c.5: AER: Corrected error received: id=00e5 pcieport 0000:00:1c.5: can't find device of ID00e5
Reproduced on 4.2 and on linus master as of today, using x86_64_defconfig.
Apart from the log spam, there is no user-visible effect that I'm aware of. Booting with pci=nomsi makes the messages go away.
Any thoughts, is this something worth looking into in more detail?
