Public bug reported:
I update the kernel images from update-manager this morning on my Ubuntu
14.10 system running on my laptop.
I had started backintime-gnome to take a backup of my home directory on
an external seagate drive connected to a 4 port USB hub. This is
something I do almost daily
I was editing a desktop shortcut on nano when suddenly I saw a black
screen with a lot of dumps and messages from the kernel (or what seemed
like the kernel). The screen was frozen - no mouse movement or keyboard
movement would restore it. I had to force a restart using the power
button.
This is the first time I have encountered something like this.
