I have a similar problem on the exact same architecture. Nevertheless, I
don't think my problem depends on how long the computer stays suspended.
>From what I can see, as soon as I close the lid I know if resume will
work fine or not:

- if the suspend light starts blinking after a few seconds, the computer will resume fine when openning the lid
- if the suspend light stays on, I know resume will not work

On this same machine I had no problem with Ubuntu 13.10. It started when
I cleanly installed 14.04.

I reported this problem a lot of time using the message boxes that
appear when I force reboot my laptop (probably around 50 times now as I
always click on "Report"). Each time I reboot, I can see at least 6 such
message boxes. Nevertheless, I can't find these automatic reports.
