I have the same problem on a Lenovo L520 (i5-2520M, 8GB RAM) running Ubuntu 11.10 (Ubuntu 3.0.0-17.30-generic-pae 3.0.22). The issue seems to occur when memory usage is close to or shortly beyond 4GB. Instead of hibernating the system remains running with screen locked. In most cases, I can just unlock, do a suspend/resume cycle and then hibernate the system successfully.
