** Description changed: After attaching a Mediatek mt76x2u based USB Wifi network adapter the system (Ubuntu 20.04.1 LTS linux version 5.4.0-58-generic) hangs My findings after some testing: - A freshly installed Ubuntu 20.04 (for testing purposes) with an outdated kernel 5.4.0-26 is not affected as the USB Wifi network adapter works without any problems. - After updating this system to kernel version 5.4.0-58 the problem can be reproduced. - After upgrading to Ubuntu 20.10 with kernel version 5.8.0-33 the USB Wifi network adapter works without any problems. So I guess it could be a software problem (maybe linux-image oder linux-modules?). + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27.14 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: joerg 821 F.... pulseaudio + CasperMD5CheckResult: skip + DistroRelease: Ubuntu 20.04 + InstallationDate: Installed on 2020-03-14 (291 days ago) + InstallationMedia: Xubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) + IwConfig: + enp0s25 no wireless extensions. + + lo no wireless extensions. + MachineType: FUJITSU ESPRIMO P7936 + NonfreeKernelModules: nvidia + Package: linux (not installed) + ProcEnviron: + LANGUAGE=de_DE + TERM=xterm-256color + PATH=(custom, no user) + LANG=de_DE.UTF-8 + SHELL=/bin/bash + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-58-generic root=UUID=62b871bf-f08a-4cd3-90a5-d6e3d83c7e9c ro quiet splash + ProcVersionSignature: Ubuntu 5.4.0-58.64-generic 5.4.73 + PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon. + RelatedPackageVersions: + linux-restricted-modules-5.4.0-58-generic N/A + linux-backports-modules-5.4.0-58-generic N/A + linux-firmware 1.187.6 + RfKill: + + Tags: focal + Uname: Linux 5.4.0-58-generic x86_64 + UpgradeStatus: Upgraded to focal on 2020-12-27 (2 days ago) + UserGroups: N/A + _MarkForUpload: True + dmi.bios.date: 04/21/2011 + dmi.bios.vendor: FUJITSU // Phoenix Technologies Ltd. + dmi.bios.version: 6.00 R1.06.3012.A1 + dmi.board.name: D3012-A1 + dmi.board.vendor: FUJITSU + dmi.board.version: S26361-D3012-A1 + dmi.chassis.type: 6 + dmi.chassis.vendor: FUJITSU + dmi.chassis.version: C$PIP1 + dmi.modalias: dmi:bvnFUJITSU//PhoenixTechnologiesLtd.:bvr6.00R1.06.3012.A1:bd04/21/2011:svnFUJITSU:pnESPRIMOP7936:pvr:rvnFUJITSU:rnD3012-A1:rvrS26361-D3012-A1:cvnFUJITSU:ct6:cvrC$PIP1: + dmi.product.name: ESPRIMO P7936 + dmi.sys.vendor: FUJITSU ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1909474/+attachment/5447926/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1909474 Title: System hangs after attaching Mediatek mt76x2u based USB Wifi network adapter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1909474/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
