Do you mean we can restore an image saved by v2.6.12 into v2.6.24? I.e. a 2.6.24 kernel will be able to run a 2.6.12 kernel's hibernation image, with all the kernel internal data from v2.6.12, etc? No way can that work. Ingo _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
