Hi Rafael, I tried with resume=/dev/hdb2. In this case while booting its giving swsusp:Suspend partition has wrong signature? And after suspending using echo shutdown > /sys/power/disk echo disk > /sys/power/state It gives kernel panic. I am not able to get what is happening !!! Do I need to add anything in my init file( like adding echo > /proc/suspend2/do_resume in case of suspend2 )? -----Original Message----- From: Rafael J.
