There were mentions of it happening after a resume from hibernate. Teo, could you please confirm whether or not you've used hibernate again and if it has triggered the bug? You mention later that it happens randomly, but I just want to make it very certain that it can't be reliably triggered by hibernation... rather than assuming anything.
To pinpoint this to an update that could have caused this issue, it would be useful to have /var/log/apt/history.log for 2014-08-05 and a few days earlier, if you still have that; along with if you remember when the computer had last been rebooted before you did last reboot you mention in this bug report. I realize this is a long time ago, but if you remember, or if you usually shut down your computer every few days, etc. then it can help figuring out from the apt history log whether a specific package was updated around the same time and could be the cause of the issue, or be a trigger for a BIOS bug. Meaningful packages could still be acpi-support, linux, etc...
