[Bug 1550311] [NEW] Ubuntu stuck at boot screen after latest kernel update

[Alexander Rechsteiner]

Public bug reported:

The last  update performed by the "Software Updater" application has
broken my system. When booting, the screen will be stuck at the Ubuntu
logo seen here:  http://i.imgur.com/nfVflMN.png

When I boot into Grub and choose to use the previous kernel
(3.19.0-43-generic) then I can boot without a problem:

The kernel causing trouble is 3.19.0-51-generic

I'm using Ubuntu on VMWare Workstation 11.1.3 build-3206955.
