For the last days hibernate was broken (reboot after about three seconds after clicking the button, Debian Wheezy 7.8 with Gnome). Hibernate works, if I call echo 0 > /sys/devices/system/cpu/cpu1/online If I then call echo 1 > /sys/devices/system/cpu/cpu1/online the system crashes (immediate reboot), no matter if the system was hibernated after the "echo 0..." or not. Because hibernate is broken for a few days now, I suppose the update from kernel package 3.2.63-2+deb7u2 to 3.2.65-1 broke the hibernate function.

I just see that Debian maintainer benh fixed this problem: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774526
