Observed in 3.13.0-151-generic and -149-generic. Using latest virtualbox package 5.2.12-122591~Ubuntu~trusty from download.virtualbox.org. Same behaviour occurred in 5.2.10 and 5.2.8. Tried kernel versions -147 -145 -144 and -143. Of these, -147 -145 and -144 exhibited problems with suspend/resume without virtualbox running (would suspend once and then subsequently fail to suspend at all). Currently stuck on using kernel version 3.13.0-143 due to this issue. Ubuntu 14.04 latest. --- ApportVersion: 2.14.1-0ubuntu3.29 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: avdd 2262 F.... pulseaudio /dev/snd/controlC0: avdd 2262 F.... pulseaudio CRDA: country AU: (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ 40), (3, 23) (5250 - 5330 @ 40), (3, 23), DFS (5735 - 5835 @ 40), (3, 30) CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2014-05-03 (1509 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 20CMCTO1WW Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-143-generic root=UUID=e616202b-b92a-4320-a7e7-e6ec2ee05c7e ro video.use_native_backlight=1 ProcVersionSignature: Ubuntu 3.13.0-143.192-generic 3.13.11-ckt39 RelatedPackageVersions: linux-restricted-modules-3.13.0-143-generic N/A linux-backports-modules-3.13.0-143-generic N/A linux-firmware 1.127.24 Tags: trusty Uname: Linux 3.13.0-143-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip docker lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 06/19/2015 dmi.bios.vendor: LENOVO dmi.bios.version: N10ET36W (1.15 ) dmi.board.asset.tag: Not Available dmi.board.name: 20CMCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN10ET36W(1.15):bd06/19/2015:svnLENOVO:pn20CMCTO1WW:pvrThinkPadX250:rvnLENOVO:rn20CMCTO1WW:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.name: 20CMCTO1WW dmi.product.version: ThinkPad X250 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1778039/+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
