RTL8723BE found on some ASUSTek laptops, such as F441U and X555UQ with subsystem ID 11ad:1723 are known to output large amounts of PCIe AER errors during and after boot up, causing heavy lags and at times lock-ups:
pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5 pcieport 0000:00:1c.5: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID) pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 pcieport 0000:00:1c.5: [ 0] RxErr
Disable ASPM on this combo as a quirk.
This patch is a revision of a previous patch (linked below) which attempted to disable ASPM for RTL8723BE on all Intel Skylake and Kaby Lake PCIe bridges. I take a more conservative approach as all known reports point to ASUSTek laptops of these two generations with this particular wireless card.
Please note, however, before the rtl8723be finishes probing, the AER errors remained. After the module finishes probing, all AER errors would indeed be eliminated, along with heavy lags, poor network throughput, and/or occasional lock-ups.
