Ubuntu Trusty kernel does not contain this commit. Before this patch, Trusty is missing: * 16e7549f045d33b0c5b0ebf19d08439e9221d40c
And this 16e7549 seems to be affected by commit 011f5ca18b53bf4c5db545f4b372d3e67a0052a4 in Trusty tree, which is a backport for e02119d5a7b4396c5a872582fddc8bd6d305a70a upstream -- 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/1809879 Title: 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 in ubuntu_btrfs_kernel_fixes hang with T Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Confirmed Bug description: Patch 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 does not exist in Trusty kernel tree. When running this test, it will hang with Trusty and gets killed by the timeout setting (2h), this will cause the following test failed with /dev/loop0 mounted issue: Invoking test 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 fix 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 Btrfs: fix infinite path build loops in incremental send The send operation processes inodes by their ascending number, and assumes that any rename/move operation can be successfully performed (sent to the caller) once all previous inodes (those with a smaller inode number than the one we're currently processing) were processed. [ .... ] Even without this loop, the incremental send couldn't succeed, because it would attempt to send a rename/move operation for the lower inode before the highest inode number was renamed/move. This issue is easy to trigger with the following steps: $ mkfs.btrfs -f /dev/sdb3 $ mount /dev/sdb3 /mnt/btrfs $ mkdir -p /mnt/btrfs/a/b/c/d $ mkdir /mnt/btrfs/a/b/c2 $ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap1 $ mv /mnt/btrfs/a/b/c/d /mnt/btrfs/a/b/c2/d2 $ mv /mnt/btrfs/a/b/c /mnt/btrfs/a/b/c2/d2/cc $ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap2 $ btrfs send -p /mnt/btrfs/snap1 /mnt/btrfs/snap2 > /tmp/incremental.send Create a readonly snapshot of '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs' in '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap1' Create a readonly snapshot of '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs' in '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap2' At subvol /tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap2 Timer expired (7200 sec.), nuking pid 27517 ERROR ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-164-generic 3.13.0-164.214 ProcVersionSignature: User Name 3.13.0-164.214-generic 3.13.11-ckt39 Uname: Linux 3.13.0-164-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Dec 27 08:26 seq crw-rw---- 1 root audio 116, 33 Dec 27 08:26 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.14.1-0ubuntu3.29 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Thu Dec 27 09:21:07 2018 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub MachineType: QEMU Standard PC (i440FX + PIIX, 1996) PciMultimedia: ProcFB: 0 cirrusdrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-164-generic root=UUID=576666e8-9e7f-40ee-934e-f1dce18323e5 ro console=ttyS0,115200n8 RelatedPackageVersions: linux-restricted-modules-3.13.0-164-generic N/A linux-backports-modules-3.13.0-164-generic N/A linux-firmware 1.127.24 RfKill: Error: [Errno 2] No such file or directory: 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/01/2014 dmi.bios.vendor: SeaBIOS dmi.bios.version: Ubuntu-1.8.2-1ubuntu1 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-xenial dmi.modalias: dmi:bvnSeaBIOS:bvrUbuntu-1.8.2-1ubuntu1:bd04/01/2014:svnQEMU:pnStandardPC(i440FX+PIIX,1996):pvrpc-i440fx-xenial:cvnQEMU:ct1:cvrpc-i440fx-xenial: dmi.product.name: Standard PC (i440FX + PIIX, 1996) dmi.product.version: pc-i440fx-xenial dmi.sys.vendor: QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1809879/+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
