What could be the cause for (multiple) ASPM errors when integration a 60-series Wi-Fi module with PCIe interface with a Jetson-nano host processor?

PCIE Active State Power Management (ASPM) is enabled by default in powersave mode in the stock nVidia kernel image. This causes correctable errors.

ASPM support needs to be disabled either by changing the kernel config by removing ASPM or by a run time change via

/sys/module/pcie_aspm/parameters/policy, set to [performance]. 

The latter however has to be done upon every boot.
