I can't give you any concrete advice yet, but what's the difference between the problematic system and the others (architecture, GUI/Desktop Environment, login manager etc)? On Thu, Jan 16, 2014 at 12:43 AM, wrote:

Hello,

Resume from suspend in RAM fails even though I have followed the Arch Wiki recommendations, with latest 3.12.7 kernel (and before). The 'resume' hook has been added for mkinitcpio and the machine goes to suspend from the command line (pm-suspend) with no GUI enabled.

All keyboard and mouse lights are off and the screen is just black with no backlight. I can't even login through SSH and can't get any PM debug info.

It happens on one particular machine only and I'm quite stuck with it.

Any suggestions to solve this ? I can provide other relevent information if required.

Thanks.

Both use KDE, kdm as login manager fglrx from AMD website. On the failing machine, I tried fglrx from the AUR with same results. The radeon driver fails to load because of lack of UMS support in the kernel. In any case, without any GUI up, it still does not resume properly. Detailed hardware differences are below, sorry if too verbose. I must say that on the problematic machine, suspend-resume works well with kernel 3.8.7, a custom build (not really knowledgeably), with which I'm stuck since long. I have not yet tested linux-lts as the wiki suggests, will do so ASAP. Thanks for considering. ******************************************************************************** Machine 1 : resume succeeds $ uname -a Linux machine1 3.11.6-1-ARCH #1 SMP PREEMPT Fri Oct 18 23:22:36 CEST 2013 x86_64 GNU/Linux $ lspci 00:00.0 Host bridge: Advanced Micro Devices, Inc.

And see if that gives you any better luck.

Unfortunately, no better luck.

Then I'm afraid I'm out of ideas. Sorry to disappoint.

Hi, Perhaps this patch solves the problem: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c1... -- Peter
