** Description changed: A few days ago, I let update-manager upgrade my kernel from 4.18.0-13 to 4.18.0-14. Since then, my system is unable to boot. It freezes after printing fb: switching to inteldrmfb from VESA VGA but before it gets around to asking me the passphrase for my encrypted main partition. (At first I thought it was a problem with cryptsetup because it never got to that prompt, but now I'm pretty sure it's something to do with changing video mode.) However, if I use the grub menu to select the older 4.18.0-13, the system boots just fine. It looks very much like a bug introduced between 4.18.0-13 and 4.18.0-14. Additionally, if I boot 4.18.0-14 in maintenance mode, the kernel modesetting does not happen, and the system boots just fine. (Except for the 1980s-style low-res video, that is.) This seems like good evidence that it's a problem with setting the video mode. - I'll test with some mainline builds, but I want to get this bug report - opened before I start rebooting. + I'll test with some mainline builds, but I want to get this bug report opened before I start rebooting. + --- + ProblemType: Bug + ApportVersion: 2.20.10-0ubuntu13.2 + Architecture: amd64 + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + DistroRelease: Ubuntu 18.10 + HibernationDevice: RESUME=UUID=fb24f9f1-0e89-4ef6-a88a-fb9fc5d776c7 + InstallationDate: Installed on 2018-09-05 (155 days ago) + InstallationMedia: Lubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) + IwConfig: + enp2s0 no wireless extensions. + + lo no wireless extensions. + MachineType: System manufacturer System Product Name + Package: linux (not installed) + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.18.0-14-generic root=/dev/mapper/lubuntu--vg-root ro + ProcVersionSignature: Ubuntu 4.18.0-14.15-generic 4.18.20 + PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon. + RelatedPackageVersions: + linux-restricted-modules-4.18.0-14-generic N/A + linux-backports-modules-4.18.0-14-generic N/A + linux-firmware 1.175.1 + RfKill: + + Tags: cosmic + Uname: Linux 4.18.0-14-generic x86_64 + UpgradeStatus: Upgraded to cosmic on 2019-01-23 (16 days ago) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo wireshark + _MarkForUpload: True + dmi.bios.date: 07/22/2010 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: 1604 + dmi.board.asset.tag: To Be Filled By O.E.M. + dmi.board.name: P7H55-M PRO + dmi.board.vendor: ASUSTeK Computer INC. + dmi.board.version: Rev 1.xx + dmi.chassis.asset.tag: Asset-1234567890 + dmi.chassis.type: 3 + dmi.chassis.vendor: Chassis Manufacture + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1604:bd07/22/2010:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP7H55-MPRO:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: + dmi.product.family: To Be Filled By O.E.M. + dmi.product.name: System Product Name + dmi.product.sku: To Be Filled By O.E.M. + dmi.product.version: System Version + dmi.sys.vendor: System manufacturer ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1815152/+attachment/5236893/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815152 Title: kernel hangs on boot after "fb: switching to inteldrmfb from VESA VGA" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1815152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
