Linux Suspend Bug

Linux Suspend Bug

[Tabor Kvasnicka]

The mainline upstream version of the kernel has a bug that won't allow
for my computer to fully suspend.

Link to bug: https://bugzilla.kernel.org/show_bug.cgi?id=87961

I have provided information based on the bug reporting instructions, but
I will provide any other information you need to help fix this problem.

I did not take time to report any of this already, but I randomly see the 
following with 3.18-rc2/3 with a ThinkPad T520:

1) On hibernating the ThinkPad sometimes does not switched of. The power LED 
is blinking as if its still suspending. It completely saves the hibernation 
image tough, cause if I switch it off hardly then it comes up with the 
hibernation image just nice. This happened several times, but not it doesn´t 
happen always.

2) Today on resuming from hibernating I just got a black screen. I switched off 
manually and the machine booted regularily after switching it on again.

I didn´t report any of this, cause I fear this would take a lot of time to 
bisect or debug properly. And I am not willing to spend that time currently 
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 messages 
so I can make a photo from the display. But right now… all I have is either 
desktop lock screen or black screen without any ability to interact with the 
machine. Well… I didn´t try SSHing to it, from another laptop so far. At least 
for the second scenario this might work, but I am quite sure it wouldn´t work 
for the first.

I think there is some regression regarding hibernation with 3.18 over 3.17.
