apport information ** Description changed:
My home server/router/access point runs under Ubuntu 18.04.4 with all updates and has 2 wifi adapters operated by hostapd one is USB AR9271 (0cf3:9271, driver ath9k_htc), another is PCIe Intel AC 9260 (8086:2526, driver iwlwifi). with kernel 4.15.0-88 it worked quite stable, with reboots required mostly after kernel upgrades (much less frequent reboots due to panics) with kernel 4.15.0-91 and -96 it started rebooting by itself by panic when a lot of activity happening via Intel 9260. In /etc/sysctl* I have kernel.panic=10 , kernel.softlockup_panic=1 and kernel.panic_on_oops=1 overrides of default values. In dmesg logs preceding the reboot, I see multiple warnings with stacks inside iwl_mvm functions which I could provide by apport. Also, multiple messages like "Command LQ_CMD: a command is already active!" or "Error sending LQ_CMD: time out after 2000ms" Unfortunately I run this box headless and I don't have another wired Ethernet host to capture its panics by netconsole The rest of hardware is pretty standard. Asus B85M-G mobo, Core i3-4130T CPU, nothing overly special. More details I would provide in your further requests but the current kernel behavior is very annoying. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.14 + Architecture: amd64 + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/hwC1D0', '/dev/snd/pcmC1D2c', '/dev/snd/pcmC1D1p', '/dev/snd/pcmC1D0c', '/dev/snd/pcmC1D0p', '/dev/snd/controlC1', '/dev/snd/hwC0D0', '/dev/snd/pcmC0D10p', '/dev/snd/pcmC0D9p', '/dev/snd/pcmC0D8p', '/dev/snd/pcmC0D7p', '/dev/snd/pcmC0D3p', '/dev/snd/controlC0', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + DistroRelease: Ubuntu 18.04 + HibernationDevice: #RESUME=UUID=f7bcdeb1-6c61-4012-81c4-a43a492ffb6e + InstallationDate: Installed on 2009-11-01 (3810 days ago) + InstallationMedia: Kubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) + MachineType: ASUS All Series + Package: linux (not installed) + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-96-generic root=/dev/mapper/vg00-root64 ro rootflags=commit=3600 rootflags=commit=3600 loop.max_part=63 + ProcVersionSignature: Ubuntu 4.15.0-96.97-generic 4.15.18 + PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon. + RelatedPackageVersions: + linux-restricted-modules-4.15.0-96-generic N/A + linux-backports-modules-4.15.0-96-generic N/A + linux-firmware 1.173.17 + RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' + Tags: bionic + Uname: Linux 4.15.0-96-generic x86_64 + UpgradeStatus: Upgraded to bionic on 2010-10-11 (3466 days ago) + UserGroups: adm admin audio cdrom dialout dip disk dos fuse jabber kvm libvirt libvirtd lpadmin plugdev proxy pulse pulse-access sambashare src + _MarkForUpload: True + dmi.bios.date: 07/22/2015 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 2501 + dmi.board.asset.tag: To be filled by O.E.M. + dmi.board.name: B85M-G + dmi.board.vendor: ASUSTeK COMPUTER INC. + dmi.board.version: Rev X.0x + dmi.chassis.asset.tag: Asset-1234567890 + dmi.chassis.type: 3 + dmi.chassis.vendor: Chassis Manufacture + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr2501:bd07/22/2015:svnASUS:pnAllSeries:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnB85M-G:rvrRevX.0x:cvnChassisManufacture:ct3:cvrChassisVersion: + dmi.product.family: ASUS MB + dmi.product.name: All Series + dmi.product.version: System Version + dmi.sys.vendor: ASUS ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1871430/+attachment/5348890/+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/1871430 Title: iwlwifi/iwlmvm & Intel 9260 made kernel unstable since 4.15.0-91 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
