Tested on 12.04, and also hangs there BUT I found the 'cause' of it.
When I received this laptop I installed a new half size mini PCIE
wireless card (Intel based) and that seems to cause the hang somehow.
When I remove the wireless card or reinstall the old original one
modprobing acer-wmi
Original card with no problems:

Forgot to mention that I indeed also had tested it with v3.13-rc3-trusty
kernel AMD64. I will test again to be sure and update accordingly.

I tested with
- v3.13-rc3: modprobing acer-wmi after boot results in same hang/10s wait
- latest daily: daily/2013-12-19-trusty : same issue.
