Can you hold down Alt and SysRQ and press S and then B when it is stuck? Does that immediately reboot the machine?
Also try suspending from the console instead of X: 1) Press CTRL-ALT-F1 to switch to the console 2) Run sudo -s 3) Run echo mem > /sys/power/state Does this resume? Press CTRL-ALT-F7 to switch back to X. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760842 Title: Natty Narwhal/Sandy Bridge Suspend Fails -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
