The bisect reported commit 8d796174763c89ec63b45699665d66ddf2050296 as the first bad commit. This really doesn't make sense. That commit is just a start release.
However, I still built a test kernel with that commit reverted. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1640297 Can you test that kernel and report back if it has the bug or not? -- 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/1640297 Title: 16.04.1 LTS hang during boot 4.4.0-45-generic with /etc/crypttab. Boots fine in 4.4.0-42-generic and older Status in linux package in Ubuntu: In Progress Bug description: System hangs during boot with 4.4.0-45-generic if /etc/crypptab contains a valid entry. Passphrase prompt never seen. Black screen with blinking underscore in upper left corner. Repeated attempts to type passphrase have no effect. There are two workarounds: 1) Comment out line referring the encrypted partition in /etc/crypttab and /etc/fstab. Mount the partition manually after boot completes 2) Boot in 4.4.0-42-generic which works as do earlier versions. i.e. the user provides passphrase at the prompt during boot and the system finishes booting robert@kalymnos:~$ cat /etc/crypttab spare2 UUID=498b08bb-5e6b-4ddf-8b37-e059665a34e6 none luks robert@kalymnos:~$ grep mapper /etc/fstab /dev/mapper/spare2 /spare2 ext4 defaults 0 2 --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: robert 2413 F.... pulseaudio /dev/snd/controlC0: robert 2413 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=291e75f9-3814-499b-bbb2-f385c164b942 InstallationDate: Installed on 2016-08-18 (83 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) IwConfig: lo no wireless extensions. enp0s25 no wireless extensions.
