Public bug reported: Hello,
I am finding that the network adapter " Network controller: Intel Corporation Wireless 7260 (rev bb) " (iwlwifi) is reported as disabled, or not present after a lengthy suspend. This is an identical issue to those reported for Realtek, but I have not found an existing report for Intel. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779817 This was no a problem in 16.04 or 17.10 with the identical hardware. 18.04 was installed clean. Happy to provide more information, however, I am not exactly sure what information to provide? Thanks in advance, Description: Ubuntu 18.04.1 LTS Release: 18.04 02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev bb) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070] 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, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 46 Region 0: Memory at e3500000 (64-bit, non-prefetchable) [size=8K] Capabilities: [c8] 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: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee08004 Data: 4022 Capabilities: [40] Express (v2) Endpoint, MSI 00 DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s <512ns, L1 unlimited ExtTag- AttnBtn- AttnInd- PwrInd- RBE+ FLReset+ SlotPowerLimit 0.000W DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- RlxdOrd+ ExtTag- PhantFunc- AuxPwr+ NoSnoop+ FLReset- MaxPayload 128 bytes, MaxReadReq 128 bytes DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr+ TransPend- LnkCap: Port #0, Speed 2.5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s <4us, L1 <32us ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp- LnkCtl: ASPM L1 Enabled; RCB 64 bytes Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- DevCap2: Completion Timeout: Range B, TimeoutDis+, LTR+, OBFF Via WAKE# DevCtl2: Completion Timeout: 16ms to 55ms, TimeoutDis-, LTR+, OBFF Disabled LnkCtl2: Target Link Speed: 2.5GT/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: [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] Device Serial Number f0-42-1c-ff-ff-c7-15-8c Capabilities: [14c v1] Latency Tolerance Reporting Max snoop latency: 71680ns Max no snoop latency: 71680ns Capabilities: [154 v1] Vendor Specific Information: ID=cafe Rev=1 Len=014 <?> Kernel driver in use: iwlwifi Kernel modules: iwlwifi ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788073 Title: Wifi adapter not found after suspend (iwlwifi) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1788073/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
