Dell LAtitude E6430 with CPU Intel® Core™ i5-3210M, 64 bits, no longer boots after updating 14.04 LTS system to kernel 3.13.0-66. It hangs off after completion of the password. Back to the 3.13.0-64 kernel works, but still with a system error, pending since about the beginning of the year (beginning approximately for the kernel 3.13.0-40) and never corrected by subsequent upgrades. It seems that the system 14.04 LTS is going worse and worse on this computer. Is there a solution ?
Buggy versions of the Linux kernel were uploaded on October 7 to trusty-proposed and vivid-proposed. Corrected replacement packages are about to be uploaded - see bug #1503655.
- Version 3.13.0-66.107 (trusty) will be replaced by version 3.13.0-66.108
- Version 3.19.0-31.35 (vivid) will be replaced by version 3.19.0-31.36
The developer Luis Henriques has made the updated packages for amd64 systems available in advance; please see this bug comment.

The corrected packages have now replaced the buggy ones in trusty-proposed and viviv-proposed.
First of all kernel 3.19.0-31 is not available in any Ubuntu stable repositories.
You got it installed because you enabled
proposed software source in System Settings -> Software & Updates.
It is not recommended and you did it at your own risk.
You can always boot with a previous kernel using grub menu. Then you can install Synaptic and remove
linux-headers packages of version 3.19.0-31.
Also I recommend to disable
proposed and never enable it unless you know what are you doing!
After you do it make sure that meta-packages
linux-headers-generic for 15.04 or
linux-headers-generic-lts-vivid for 14.04.3 are installed.
Otherwise the kernel will not get normal upgrades.
To get into grub menu you need to hold Shift or Esc at boot depending on your hardware.
Similar problem with my Ubuntu 14.04 LTS, on Dell Inspiron n5040, Intel Pentium P6200, and the version of the kernel. My temporary solution is to reinstall this kernel, and now I'm working with previous version: 3.13.0-65.
