** Description changed: This seems to be a bug that has regressed, I have encountered the same issue as 2 other reports: LP: #1349897 Running kernel: 3.13.0-46-generic This is replicated over many compute nodes (KVM) running OpenStack. The workaround is to disable KSM: echo 2 > /sys/kernel/mm/ksm/run This fixes the issue temporarily. + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Mar 15 02:22 seq + crw-rw---- 1 root audio 116, 33 Mar 15 02:22 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.7 + 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 14.04 + InstallationDate: Installed on 2015-03-15 (8 days ago) + InstallationMedia: Ubuntu-Server 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.3) + Lsusb: + Bus 002 Device 002: ID 8087:0024 Intel Corp.
