If you haven't set pcie_aspm=force, you aren't allowed to change the value of /sys/module/pcie_aspm/parameters/policy
Writing worked until some kernel version (iirc <3.0), but then kernel hackers changed its behaviour, except you set pcie_aspm=force in your bootloader's boot cmd.

Please disable the module by default or silence the message output.
