Can you retry with current drm-fixes? There has been a fix which might help at least for the UVD errors. (In reply to comment #1) > Can you retry with current drm-fixes?

You can revert the patch referenced in that bug to fix that. danvet supposed has a v2 of that patch which doesn't break resume. Also, does it work any better if you drop all the pm-suspend quirks? You shouldn't need them for KMS. (In reply to comment #4) > The atombios messages are due to bug 67043.

You > shouldn't need them for KMS. ok, so reverting the original patch and applying the attached one is the correct order ? or shall it be applied to current source ? - (probably the former) - will try I hesitantly will give it a try without the quirks - up until now the box always would hardlock without those quirks - both on xf86-video-ati or fglrx but ... it might work already without quirks since via Xfce it suspended and resumed successfully to ram 2-3 times already from the panel menu with non(new)-DPM so far thanks !

(so the uvd error after resume & gpu lock/hang) switch to gcc 4.7* ? would that make a change ? the gcc 4.8*/4.8.1* related issues are already solved, right ? do you need more info ? Maybe unrelated to this bug report, but with today's Linus' master (04012e3076943f17c8cfc77a196701c8f0b8964f) the only suspend/resume issue left is that I get: [drm:rv770_stop_dpm] *ERROR* Could not force DPM to low. in dmesg upon resume. That is before the 'ring' and 'uvd' messages. It seems harmless, I didn't notice any problems. It can switch power levels later on, play videos via uvd... it just seems to try to do something with dpm too early in the resume process.

Thanks a lot to everyone for the fixes & work ! on a side-note: the hardlocks I experienced in the past might have been due to BFQ & some exotic setup/tweaks/additional patches that I'm using so perhaps no hardlocks with the DPM code so far :) I had to restart due to some other issue and it wouldn't "successfully" resume anymore: the lag/slowdown was there again forcing performance_level to "low" or "auto" didn't seem to make a difference so I'll try a 3.11-rc2* kernel in the weekend then - provided of course that it runs without other problems could it be related to reboot from Windows (windows 8 -> linux) that resume worked properly ?
