On a laptop with intel processor and graphics card, the return from suspension with 3.13 kernel goes smoothly. Since this bug is a regression, it's possible to do a bisect between v3.13 and v3.14-rc1? After resume, is the system totally dead or you can still remote login to it? If you can still remote login, please grab the dmesg and attach here. BTW, you can also do some basic debugging per: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt Created attachment 124981 [details]

On return from suspension remains in black screen and no longer functional ubuntu 14.04. Reboot is required. The dmesg you attached doesn't seems to be the one after the system is resumed. If it's not possible to get these information, please follow comment #2 to do a git-bisect to find the offending commit. Created attachment 124991 [details]

I hope to help ... The dmesg_after file doesn't have any information about system suspend/resume, does it actually get created? Did you try this document? https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt Is your CPU IA-64(Itanium) or a normal pentium/core i3/i5/i7 one?

If your system is dead on resume, then there is no way to see errors unless you have a serial port. Please test the following things to see if any driver has issues first: # cd /sys/power # echo devices > pm_test # echo mem > state Check dmesg, see if any errors there.

Did you follow the steps in comment #18? In test # cd / sys / power # Echo devices> pm_test # Echo mem> states laptop monitor could not be functionally different than the distorted image, I had to stop the button.Thank you! What do you mean by 'the distorted image' and 'stop the button'? Can you please be more detailed? Thanks. Created attachment 126071 [details]

I took a picture monitor.
Images on the screen are distorted and unstable if you move the mouse or press Enter. I do not know what other details you give, the fact is that the laptop is inoperable, are forced to stop on the button. This suggests the graphics driver has issues dealing with PM transition. I'll re-assign the bug to GPU/Raedon category. I guessed long ago that the problem would be amd radeon open source video drivers. A while before I reinstalled ubuntu 14.04 because of errors caused by my attempts to change some parameters to kernel 3.14. Therefore I returned to the kernel ubuntu 3.13, but of course the same problems return from suspension. Thank you! And hopefully before the official launch ubuntu 14.04 the problem to be solved. paul@Satellite-L500D:~$ sudo lspci -vnn | grep -A12 VGA [sudo] password for paul: 02:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
