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 http://bugs.debian.org/652869 for details. Please consider reverting the patch from stable until this is resolved.
Thanks, Jonathan
