Bug 91321

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.
