[Fix] Protect against cases when ICM is not set. [Test] User confirmed the additional patch works. [Regression Potential] Low. It adds a simple logic to avoid NULL dereference. ===Original Bug Report=== Ubuntu Desktop 18.04 release version, running on a Lenovo T570 laptop. Sometimes, at boot, the system goes into Emergency Mode.
