Kai-Heng,
Yes, but with ASPM disabled unfortunately even ASPT doesn't help enough.

Is cooling the NVMe is your goal? 4.10.0-19 already has NVMe APST
support. No sure if PCIe ASPM matters though.

I sent a follow up email to Lenovo but don't expect to hear back from
them until sometime after next Monday.

Talking to Matthew Garrett on irc he said that he thinks this may only
be fixable via an UEFI change.
04:33 < ccheney> anyone know if it is possible to change a setting in LnkCap on
a pci device? My pcie ports apparently have 'ASPM not supported' set and I need
to turn it on somehow

The setpci commands I used modified the LnkCtl option but not the LnkCap
values. I'm not sure but suspect that the LnkCap values are what are
causing the problem.
