I did not take time to report any of this already, but I randomly see t= he=20 following with 3.18-rc2/3 with a ThinkPad T520: 1) On hibernating the ThinkPad sometimes does not switched of. The powe= r LED=20 is blinking as if its still suspending. It completely saves the hiberna= tion=20 image tough, cause if I switch it off hardly then it comes up with the=20 hibernation image just nice. This happened several times, but not it do= esn=C2=B4t=20 happen always. 2) Today on resuming from hibernating I just got a black screen. I swit= ched off=20 manually and the machine booted regularily after switching it on again. I didn=C2=B4t report any of this, cause I fear this would take a lot of= time to=20 bisect or debug properly. And I am not willing to spend that time curre= ntly=20 since there are more important things for me to attend to. Maybe if there is an easy way to have it in text console and give all m= essages=20 so I can make a photo from the display. But right now=E2=80=A6 all I ha= ve is either=20 desktop lock screen or black screen without any ability to interact wit= h the=20 machine. Well=E2=80=A6 I didn=C2=B4t try SSHing to it, from another lap= top so far. At least=20 for the second scenario this might work, but I am quite sure it wouldn=C2= =B4t work=20 for the first. I think there is some regression regarding hibernation with 3.18 over 3= =2E17. Ciao, --=20 Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
