This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

It can be cherry-picked into B/D/E/F, we don't run this test in X so it can be skipped. Note that we don't have 852c8cbf in B/D, but I think it's still OK to fix them as the change is really small, and if they got that patch in the future we don't need to look back on this. == Test == Patch tested directly on KVM nodes. It works as expected. == Regression Potential == Low, trivial change limited to testing tools. == Original Bug Report == Issue found on Eoan this test will timeout quite randomly before the test can complete: 1st attempt: # [23] ftrace - function trace on module [PASS] # [24] ftrace - function profiling# not ok 1 selftests: ftrace: ftracetest # TIMEOUT 2nd attemp: # [31] Kprobe dynamic event - adding and removing [PASS] # [32] Kprobe dynamic event - busy event check# not ok 1 selftests: ftrace: ftracetest # TIMEOUT 3rd attempt: # [35] Kprobe event string type argument [PASS] # [36] Kprobe event symbol argument# not ok 1 selftests: ftrace: ftracetest # TIMEOUT ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: linux-image-5.3.0-40-generic 5.3.0-40.32 ProcVersionSignature: User Name 5.3.0-40.32-generic 5.3.18 Uname: Linux 5.3.0-40-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Feb 21 09:05 seq crw-rw---- 1 root audio 116, 33 Feb 21 09:05 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.11-0ubuntu8.2 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Fri Feb 21 09:09:06 2020 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub MachineType: QEMU Standard PC (i440FX + PIIX, 1996) PciMultimedia: ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash ProcFB: 0 cirrusdrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.3.0-40-generic root=UUID=29438a95-0e7a-484b-a1fb-527f0e3d2e06 ro console=tty1 console=ttyS0 RelatedPackageVersions: linux-restricted-modules-5.3.0-40-generic N/A linux-backports-modules-5.3.0-40-generic N/A linux-firmware 1.183.4 RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/01/2014 dmi.bios.vendor: SeaBIOS dmi.bios.version: 1.10.2-1ubuntu1 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-bionic dmi.modalias: dmi:bvnSeaBIOS:bvr1.10.2-1ubuntu1:bd04/01/2014:svnQEMU:pnStandardPC(i440FX+PIIX,1996):pvrpc-i440fx-bionic:cvnQEMU:ct1:cvrpc-i440fx-bionic: dmi.product.name: Standard PC (i440FX + PIIX, 1996) dmi.product.version: pc-i440fx-bionic dmi.sys.vendor: QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1864172/+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
