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

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. === 00:1b.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Root Port #17 (rev f1) (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 122 Bus: primary=00, secondary=01, subordinate=01, sec-latency=0 I/O behind bridge: 0000f000-00000fff Memory behind bridge: df100000-df1fffff Prefetchable memory behind bridge: 00000000fff00000-00000000000fffff Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort+ <SERR- <PERR- BridgeCtl: Parity- SERR- NoISA- VGA- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: [40] Express (v2) Root Port (Slot+), MSI 00 DevCap: MaxPayload 256 bytes, PhantFunc 0 ExtTag- RBE+ DevCtl: Report errors: Correctable+ Non-Fatal+ Fatal+ Unsupported+ RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop- MaxPayload 128 bytes, MaxReadReq 128 bytes DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr+ TransPend- LnkCap: Port #17, Speed 8GT/s, Width x4, ASPM not supported, Exit Latency L0s <1us, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkSta: Speed 8GT/s, Width x4, TrErr- Train- SlotClk+ DLActive+ BWMgmt+ ABWMgmt- SltCap: AttnBtn- PwrCtrl- MRL- AttnInd- PwrInd- HotPlug- Surprise- Slot #0, PowerLimit 25.000W; Interlock- NoCompl+ SltCtl: Enable: AttnBtn- PwrFlt- MRL- PresDet- CmdCplt- HPIrq- LinkChg- Control: AttnInd Unknown, PwrInd Unknown, Power- Interlock- SltSta: Status: AttnBtn- PowerFlt- MRL- CmdCplt- PresDet+ Interlock- Changed: MRL- PresDet- LinkState+ RootCtl: ErrCorrectable- ErrNon-Fatal- ErrFatal- PMEIntEna+ CRSVisible- RootCap: CRSVisible- RootSta: PME ReqID 0000, PMEStatus- PMEPending- DevCap2: Completion Timeout: Range ABC, TimeoutDis+, LTR+, OBFF Not Supported ARIFwd+ DevCtl2: Completion Timeout: 50us to 50ms, TimeoutDis-, LTR+, OBFF Disabled ARIFwd- LnkCtl2: Target Link Speed: 8GT/s, EnterCompliance- SpeedDis- Transmit Margin: Normal Operating Range, EnterModifiedCompliance- ComplianceSOS- Compliance De-emphasis: -6dB LnkSta2: Current De-emphasis Level: -3.5dB, EqualizationComplete+, EqualizationPhase1+ EqualizationPhase2+, EqualizationPhase3+, LinkEqualizationRequest- Capabilities: [80] MSI: Enable+ Count=1/1 Maskable- 64bit- Address: fee00218 Data: 0000 Capabilities: [90] Subsystem: Lenovo Sunrise Point-H PCI Root Port Capabilities: [a0] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [100 v1] Advanced Error Reporting UESta: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF- MalfTLP- ECRC- UnsupReq- ACSViol- UEMsk: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt+ RxOF- MalfTLP- ECRC- UnsupReq- ACSViol- UESvrt: DLP+ SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF+ MalfTLP+ ECRC- UnsupReq- ACSViol- CESta: RxErr- BadTLP- BadDLLP- Rollover- Timeout- NonFatalErr- CEMsk: RxErr- BadTLP- BadDLLP- Rollover- Timeout- NonFatalErr+ AERCap: First Error Pointer: 00, GenCap- CGenEn- ChkCap- ChkEn- Capabilities: [140 v1] Access Control Services ACSCap: SrcValid+ TransBlk+ ReqRedir+ CmpltRedir+ UpstreamFwd- EgressCtrl- DirectTrans- ACSCtl: SrcValid- TransBlk- ReqRedir- CmpltRedir- UpstreamFwd- EgressCtrl- DirectTrans- Capabilities: [220 v1] #19 Kernel driver in use: pcieport Kernel modules: shpchp ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: linux-image-4.10.0-19-generic 4.10.0-19.21 ProcVersionSignature: Ubuntu 4.10.0-19.21-generic 4.10.8 Uname: Linux 4.10.0-19-generic x86_64 ApportVersion: 2.20.4-0ubuntu4 Architecture: amd64 AudioDevicesInUse: Cannot stat file /proc/2050/fd/24: Stale file handle Cannot stat file /proc/2050/fd/25: Stale file handle USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu-mate 2046 F.... pulseaudio CasperVersion: 1.380 Date: Fri Apr 14 04:10:41 2017 LiveMediaBuild: Ubuntu-MATE 17.04 "Zesty Zapus" - Release amd64 (20170412) MachineType: LENOVO 10FMCTO ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/casper/vmlinuz.efi debug ignore_loglevel pcie_aspm.policy=powersave pcie_aspm=force file=/cdrom/preseed/hostname.seed boot=casper quiet splash --- PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
