When I was trying out the RHEL6 beta I saw this problem on a recent model top line Thinkpad T series. (A T500? It's not in front of me right now.) That machine is now running RHEL6.1 and hibernation is fine, evidenced by the fact that two days ago I unplugged it after forgetting to shut it down and it recovered just fine. I don't recall if the fixed kernel was part of the initial RHEL6.0 or not, but you might find that as the CentOS updates catch up the problem may go away. [And with respect to the 'Effecting CentOS change' thread, yes having an early RHEL test system with a license and submitting a bug report works wonders. I was motivated by wanting CentOS to work on my new laptop ...] Devin _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
