Public bug reported:
The kernel log is constantly filled with the following:
236.912499] pcieport 0000:00:1c.5: AER: Corrected error received: id=00e5
[ 236.912545] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected,
type=Data Link Layer, id=00e5(Transmitter ID)
[ 236.912553] pcieport 0000:00:1c.5: device [8086:a115] error
status/mask=00001000/00002000
[ 236.912558] pcieport 0000:00:1c.5: [12] Replay Timer Timeout
This drains battery, CPU cycles and makes the kernel log unreadable.
Adding pcie_aspm hides that:
GRUB_CMDLINE_LINUX_DEFAULT="quiet button.lid_init_state=open
pcie_aspm=off"
Present in the upstream Linux kernel (see the attachment for 4.11 rc8).
