I can't install apport on the original system where this problem was observed (Precise + LTS kernel) but I have reproduced it on a Raring install with 3.8.0-31-generic and submitted the apport information from that environment.

This was reported to the linux-ext4 list in http://marc.info/?t=138018028300003&r=1&w=2. The subsequent investigation identified the git commit 7b2b160da7661bb2ade3f924b1bd3e3084e53341 as solving the problem. We have applied this on top of tag Ubuntu-lts-3.8.0-13.22 and confirmed that it resolves the problem we are seeing. --- AlsaDevices: total 0 crw-rw---T 1 root audio 116, 1 Oct 4 19:28 seq crw-rw---T 1 root audio 116, 33 Oct 4 19:28 timer AplayDevices: Error: [Errno 2] No such file or directory ApportVersion: 2.9.2-0ubuntu8.3 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CRDA: Error: [Errno 2] No such file or directory DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=1d79e306-bed4-4cd4-8dbc-24a727ef8db6 IwConfig: Error: [Errno 2] No such file or directory Lspci: Lsusb: Error: command ['lsusb'] failed with exit code 1: unable to initialize libusb: -99 MarkForUpload: True Package: linux (not installed) PciMultimedia: ProcEnviron: LANGUAGE=en_GB:en TERM=screen PATH=(custom, no user) LANG=en_GB.UTF-8 SHELL=/bin/bash ProcFB: 0 xen ProcKernelCmdLine: root=/dev/mapper/ejbca0_systemvg-rootlv ro rootflags=subvol=@ splash quiet tmem $vt_handoff ProcVersionSignature: Ubuntu 3.8.0-31.46-generic 3.8.13.8 RelatedPackageVersions: linux-restricted-modules-3.8.0-31-generic N/A linux-backports-modules-3.8.0-31-generic N/A linux-firmware 1.106 RfKill: Error: [Errno 2] No such file or directory Tags: raring Uname: Linux 3.8.0-31-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1234662/+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
