-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1896904 Title: Intel 9560 WLAN (8086:9df0) producing computer hanging and wifi breakdown Status in linux package in Ubuntu: Confirmed Bug description: If I do video conferences for example my wifi breaks down. I'm preety sure the it happens since I updated my WiFi router (FritzBox 7590 to Firmware 7.20). I was in contact with the manufacturer. They don't know any problems. I checked dmesg and saw a lot of error messages. So i thought I should report a bug here. Some times WiFi breaks down and comes up again after a few seconds, sometimes it will not come back and I have to restart the computer. Sometimes I can't even turn of WiFi in the Ubuntu menu. Settings telling me something link "network manager not available" (not sure what the exact message is). All firmware updates are installed, I updated to the latest kernel and had the problem again. The logs generated with "ubuntu-bug linux" in this ticket are with symptom "recovers after some seconds" with massive hanging of hole Ubuntu (was not able to move mouse / press strg+alt+t to open terminal). Before I learned how to generate proper logs I saved output of dmesg. I will append some of this to this ticket. There are different error messages. Some without recovering. I will append more proper generated logs (ubuntu-bug linux) to this ticket if I get similar problems and if you would like to see them. It's a ThinkPad T490, it's Ubuntu 20.04.1 LTS, it's a "Intel Corp. Intel 9560 WLAN (8086:9df0)" WiFi card. fnpk@cl003287:~$ uname -a Linux cl003287 5.4.0-48-generic #52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux fnpk@cl003287:~$ fwupdmgr get-updates • Thunderbolt Controller has the latest available firmware version • Prometheus has the latest available firmware version • Prometheus IOTA Config has the latest available firmware version • SAMSUNG MZVLB512HBJQ-000L7 has no available firmware updates • System Firmware has the latest available firmware version • UEFI Device Firmware has the latest available firmware version • UEFI Device Firmware has the latest available firmware version • UEFI Device Firmware has no available firmware updates • UEFI Device Firmware has no available firmware updates ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-48-generic 5.4.0-48.52 ProcVersionSignature: Ubuntu 5.4.0-48.52-generic 5.4.60 Uname: Linux 5.4.0-48-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Thu Sep 24 09:06:55 2020 InstallationDate: Installed on 2020-01-10 (257 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) MachineType: LENOVO 20N2000KGE ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.4.0-48-generic root=/dev/mapper/vgubuntu-root ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.4.0-48-generic N/A linux-backports-modules-5.4.0-48-generic N/A linux-firmware 1.187.3 SourcePackage: linux UpgradeStatus: Upgraded to focal on 2020-05-12 (134 days ago) dmi.bios.date: 08/12/2020 dmi.bios.vendor: LENOVO dmi.bios.version: N2IET91W (1.69 ) dmi.board.asset.tag: Not Available dmi.board.name: 20N2000KGE dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN2IET91W(1.69):bd08/12/2020:svnLENOVO:pn20N2000KGE:pvrThinkPadT490:rvnLENOVO:rn20N2000KGE:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T490 dmi.product.name: 20N2000KGE dmi.product.sku: LENOVO_MT_20N2_BU_Think_FM_ThinkPad T490 dmi.product.version: ThinkPad T490 dmi.sys.vendor: LENOVO --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-01-10 (282 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) MachineType: LENOVO 20N2000KGE Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.4.0-51-generic root=/dev/mapper/vgubuntu-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.4.0-51.56-generic 5.4.65 RelatedPackageVersions: linux-restricted-modules-5.4.0-51-generic N/A linux-backports-modules-5.4.0-51-generic N/A linux-firmware 1.187.3 Tags: focal Uname: Linux 5.4.0-51-generic x86_64 UpgradeStatus: Upgraded to focal on 2020-05-12 (159 days ago) UserGroups: adm cdrom dip docker lpadmin lxd plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 08/12/2020 dmi.bios.vendor: LENOVO dmi.bios.version: N2IET91W (1.69 ) dmi.board.asset.tag: Not Available dmi.board.name: 20N2000KGE dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN2IET91W(1.69):bd08/12/2020:svnLENOVO:pn20N2000KGE:pvrThinkPadT490:rvnLENOVO:rn20N2000KGE:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T490 dmi.product.name: 20N2000KGE dmi.product.sku: LENOVO_MT_20N2_BU_Think_FM_ThinkPad T490 dmi.product.version: ThinkPad T490 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896904/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
