Public bug reported:
This is somewhat similar in issue to lp#1377596.
I have a "Lenovo ThinkCentre m900 Tiny" with an "Intel 600p" NVMe drive
in it.
As far as I can tell from dissembling the FADT PCIe ASPM is not set to
disabled but the ports are not enabled in UEFI during boot.
I also notice that the PCIe ASPM debug files are not in sysfs like they
normally are ie: link_state
I tried running the following manually but I think it must not be enough
as the NVMe drive does not run any cooler as it does in a system with
known working ASPM.
setpci -s 00:1b.0 0x50.B=0x3
setpci -s 00:1c.0 0x50.B=0x3
setpci -s 01:00.0 0x80.B=0x3
setpci -s 02:00.0 0x50.B=0x3
I noticed via lspci that the root ports say ASPM not supported even
though the FADT doesn't have them disabled. Is that the reason its still
not working and how do I work around that issue?
Also is there something specific I can tell Lenovo to do to fix this
issue on their end, if it can't be worked around in Linux? I have an
open case with them via the UEFI engineering team but so far its been
slow going since I don't have anything concrete to tell them to fix.
