Looking at the code for _rtl_pci_update_default_setting(), the meaning
of value 2 actually seems to be "enable ASPM on Intel platforms, and
disable on others".

But I suspect that code is not working right, because the system we
are using here is Intel-based and so my expectation would be that
value 2 leaves ASPM on and we would continue seeing the issue.
However, Jian-Hong reports it as working.

There are also some other reports that this driver doesn't work until
aspm is disabled:
