** Description changed: Greetings, I recently upgraded from the 4.4.0-31 to 4.4.0-34 kernel in Ubuntu 16.04. If I try booting from 4.4.0-34, my system freezes just after I enter my password to decrypt my hard-drive. If I ask it to boot from 4.4.0-31, everything is fine. My boot.log file: lvmetad is not active yet, using direct activation during sysinit Volume group "ubuntu-vg" not found Cannot process volume group ubuntu-vg /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. Reading all physical volumes. This may take a while... Found volume group "ubuntu-vg" using metadata type lvm2 /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. 2 logical volume(s) in volume group "ubuntu-vg" now active /dev/mapper/ubuntu--vg-root: recovering journal /dev/mapper/ubuntu--vg-root: clean, 525872/28426240 files, 91143613/113674240 blocks It's unclear to me what is going wrong. There appears to be no activity on the computer. I let the boot sequence sit for 10 minutes (way longer than an average boot time) my laptop's fan is running full-tilt. But there was no hard-drive activity. How can I find out what's going wrong? - I'm running Ubuntu 16.04 Linux on a Lenovo W530. I'm not certain what - other information would be helpful for a bug report. I would be happy - to submit whatever is deemed helpful. + I'm running Ubuntu 16.04 Linux on a Lenovo W530.
