I have the same issue. It affects Toshiba Portege R830 model. After many tries with s2ram and memory_corruption_check_size options (all of them resulted the same: blank screen, noisy fans and lack of any response). To highlight the situation I tried to suspend only from console with init=/bin/bash option.
Try of tracking down failing device gave the following result: -- 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
