Bug Description
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/
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/
WARNING: Failed to connect to lvmetad. Falling back to internal scanning.
2 logical volume(s) in volume group "ubuntu-vg" now active
/dev/mapper/
/dev/mapper/
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.
