** Description changed: I am using Ubuntu 16.04. After upgrading the kernel from 4.4.0-141.167-generic to 4.4.0-142.168-generic I am experiencing problem logging in via the tty. I am able to provide my username, but the terminal automatically submit password before I am able to type it. If I start the computer with the previous kernel (4.4.0-141.167) it works as expected. I have done strace on the tty in both scenarios while performing the login with the following command: "sudo strace -p 1572 -s 1024 -vff -o tty-login-issue/login" 4.4.0-141.167-generic (works): https://gist.github.com/ivarconr/b022d2b4cadfc654031e8a930bf4408b 4.4.0-142.168-generic (fails): https://gist.github.com/ivarconr/603409ad1f0a3343a7f44a854283befc Let me know if you need me to provide any additional details. --- ApportVersion: 2.20.1-0ubuntu2.18 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ivaosthu 3706 F.... pulseaudio /dev/snd/controlC1: ivaosthu 3706 F.... pulseaudio CurrentDesktop: i3 DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=08d4aeb0-e54b-475e-8a26-b9e8b488a314 InstallationDate: Installed on 2016-08-12 (909 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: LENOVO 20EQS2HW00 Package: linux (not installed) ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-142-generic.efi.signed root=UUID=a0472864-d2ab-4f9d-8b4c-e89db4dbd51b ro quiet nomodeset splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.4.0-142.168-generic 4.4.167 RelatedPackageVersions: linux-restricted-modules-4.4.0-142-generic N/A linux-backports-modules-4.4.0-142-generic N/A linux-firmware 1.157.21 Tags: xenial Uname: Linux 4.4.0-142-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom davfs2 dip docker lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 05/10/2016 dmi.bios.vendor: LENOVO dmi.bios.version: N1EET52W (1.26 ) dmi.board.asset.tag: Not Available dmi.board.name: 20EQS2HW00 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:bvrN1EET52W(1.26):bd05/10/2016:svnLENOVO:pn20EQS2HW00:pvrThinkPadP50:rvnLENOVO:rn20EQS2HW00:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.name: 20EQS2HW00 dmi.product.version: ThinkPad P50 dmi.sys.vendor: LENOVO + --- + ApportVersion: 2.20.1-0ubuntu2.18 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: ivaosthu 3706 F.... pulseaudio + /dev/snd/controlC1: ivaosthu 3706 F.... pulseaudio + CurrentDesktop: i3 + DistroRelease: Ubuntu 16.04 + HibernationDevice: RESUME=UUID=08d4aeb0-e54b-475e-8a26-b9e8b488a314 + InstallationDate: Installed on 2016-08-12 (909 days ago) + InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) + MachineType: LENOVO 20EQS2HW00 + Package: linux (not installed) + ProcFB: 0 EFI VGA + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-142-generic.efi.signed root=UUID=a0472864-d2ab-4f9d-8b4c-e89db4dbd51b ro quiet nomodeset splash vt.handoff=7 + ProcVersionSignature: Ubuntu 4.4.0-142.168-generic 4.4.167 + RelatedPackageVersions: + linux-restricted-modules-4.4.0-142-generic N/A + linux-backports-modules-4.4.0-142-generic N/A + linux-firmware 1.157.21 + Tags: xenial + Uname: Linux 4.4.0-142-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom davfs2 dip docker lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 05/10/2016 + dmi.bios.vendor: LENOVO + dmi.bios.version: N1EET52W (1.26 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 20EQS2HW00 + 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:bvrN1EET52W(1.26):bd05/10/2016:svnLENOVO:pn20EQS2HW00:pvrThinkPadP50:rvnLENOVO:rn20EQS2HW00:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: + dmi.product.name: 20EQS2HW00 + dmi.product.version: ThinkPad P50 + dmi.sys.vendor: LENOVO -- 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/1815122 Title: Unable to login via tty Status in linux package in Ubuntu: Confirmed Bug description: I am using Ubuntu 16.04.
