tested linus' and also drm-fixes-3.11
Comment 2 Alex Deucher 2013-08-04 15:33:21 UTC 
This looks like a UVD problem.  Do you get the same issue with dpm disabled?  Make sure your kernel has this patch:

Comment 3 Bastian Triller 2013-08-04 21:44:42 UTC 
Yep, this fails also with dpm=0. I missed the errors in dmesg as I resumed once with dpm=0.

I have built the kernel with the latest drm-fixes-3.11 (dffd4b65ca8989).

You said in comment 3 that you also had the same failure with dpm disabled, but you just changed the summary to indicate that it happens with dpm enabled.  Which is correct?  Is it only an issue with dpm enabled or does it happen regardless of whether dpm is enabled?
Comment 6 Bastian Triller 2013-08-12 19:53:15 UTC 
Wow, that was a fast answer.

Resume with dpm=0 works. With dpm=1 only with power adapter attached. Screen stays black and laptop starts heating up and I have to force off the laptop. The laptop is pingable but SSH doesn't work, neither a new session nor an open one. It makes no difference if I suspend with or without power adapter.

Works now. Tested with 3.12.0-rc6-20582e. Thanks for your work.
