Suspend and Hibernate are known issues with Linux in general, and certainly Ubuntu is no exception. For now, I would suggest the workaround in http://linux.dell.com/wiki/index.php/Ubuntu_7.10/Issues/8400M_Suspend_Hibernate-Failure (this is for nVidia, but should also works for Intel video cards). Unfortunately, expecting suspend and hibernate to work 100% of the time is not a reality at this time, but are diligently working to get there at some point.
