Sorry it's taken me so long to get back to you; the affected system is my main work computer, so I can't just go rebooting it constantly, and I've been busy with other things.
In any event, I'm afraid I haven't had much luck with these newer kernels. The bottom line is that to get the VirtualBox modules installed, I need the linux-headers-{version}-generic package, and for these newer kernels, that package depends on libssl1.1 or greater; but the 16.04 I'm using ships with libssl1.0, and I'm unwilling to upgrade that package and risk far greater (and worse) problems or a return to the old "dependency hell" issues of the 1990s. If I get the chance, I may try installing bionic on a removable drive and try to reproduce the problem in that way. -- 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/1748901 Title: System hang with Virtualbox & kernel 4.13.0-32-generic Status in linux package in Ubuntu: Confirmed Status in linux source package in Artful: Confirmed Bug description: Some (maybe all) kernels in the 4.13.0 series are hanging with Virtualbox on my Ubuntu 16.04 laptop. When I try to launch a Virtualbox VM, the VM's window appears, clears to black, and then the mouse freezes. I do NOT see any BIOS/EFI information or boot loader in the VM; the hang occurs before those messages appear. (I've tried this with the VM set for both BIOS and EFI booting with no difference.) The host computer also stops responding to pings or anything else; the only solution seems to be to do a cold reset. I've tested this on a different computer running the same kernel and the latest Ubuntu 18.04 alpha and had no problems there. Here's some data from the affected computer: $ lsb_release -rd Description: Ubuntu 16.04.3 LTS Release: 16.04 $ cat /proc/version_signature Ubuntu 4.13.0-32.35~16.04.1-generic 4.13.13 $ dpkg -s virtualbox | grep Version Version: 5.0.40-dfsg-0ubuntu1.16.04.2 This problem does NOT occur with earlier kernels, such as those in the 4.4.0 series. --- ApportVersion: 2.20.1-0ubuntu2.15 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: rodsmith 2661 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2014-05-02 (1382 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: SAMSUNG ELECTRONICS CO., LTD. 740U5M Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: \vmlinuz-4.13.0-32-generic.efi.signed ro root=/dev/mapper/hostname-trusty_crypt quiet splash initrd=\initrd.img-4.13.0-32-generic ProcVersionSignature: Ubuntu 4.13.0-32.35~16.04.1-generic 4.13.13 RelatedPackageVersions: linux-restricted-modules-4.13.0-32-generic N/A linux-backports-modules-4.13.0-32-generic N/A linux-firmware 1.157.15 Tags: xenial Uname: Linux 4.13.0-32-generic x86_64 UpgradeStatus: Upgraded to xenial on 2016-09-03 (526 days ago) UserGroups: adm cdrom dialout dip disk libvirtd lpadmin plugdev sambashare sbuild sudo vboxusers _MarkForUpload: True dmi.bios.date: 12/06/2016 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: P02AFZ.015.161206.KS dmi.board.asset.tag: No Asset Tag dmi.board.name: NP740U5M-X01US dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: SGL8815A0I-C01-G001-S0001+10.0.14393 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 31 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrP02AFZ.015.161206.KS:bd12/06/2016:svnSAMSUNGELECTRONICSCO.,LTD.:pn740U5M:pvrP02AFZ:rvnSAMSUNGELECTRONICSCO.,LTD.:rnNP740U5M-X01US:rvrSGL8815A0I-C01-G001-S0001+10.0.14393:cvnSAMSUNGELECTRONICSCO.,LTD.:ct31:cvrN/A: dmi.product.family: SAMSUNG ATIV dmi.product.name: 740U5M dmi.product.version: P02AFZ dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD.
