Seems to cause a regression. On the affected kernels (e.g., 3.1.5,
3.1.6, and 3.2-rc7) the patch has exactly the opposite of what you'd
expect --- the affected machines automatically power on a few minutes
after shutdown if and only if the patch is applied.

The affected machines all seem to be Toshiba Portege laptops.

Antonio-M. Corbi Bellot: Toshiba Portege R500
Marco Santos: Toshiba Portege Z830
Christophe Vu-Brugier: Toshiba Portege R830

Christophe tried reverting the above patch and the symptoms went away.
See for details. Please consider
reverting the patch from stable until this is resolved.
