Title:
Can't boot from new kernel 4.4.0-34. Old kernel 4.4.0-31 is fine.
Status in linux package in Ubuntu:
Incomplete
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/lvm/lvmetad.socket: connect failed: No such file or directory
WARNING: Failed to connect to lvmetad. Falling back to internal scanning.

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.
