Rohan Garg, as the logs for Trusty were provided already, no need exists to apport-collect further at this point.
** Description changed: After upgrading from Saucy to Trusty, the 3.12.0-2 kernel doesn't fully boot on my machine. I have to use the older 3.11 kernel to boot. The 3.12.0 kernel tries to boot but then seems to fail at some stage.
