   Hello,   
      
   A Debian user (Roman Savochenko, on Cc:) reports issues (freezing with   
   black screen) with a Radeon HD 8570D graphics adapter. When passing   
   `radeon.dpm=0` on the kernel commandline the problems are gone.   
      
   Is it a sensible quirk to let dpm default to 0 with that hardware? Or   
   does the behaviour depend on (e.g.) the actual monitor in use?   
      
   Or is there a bug to fix? If so, do you have a hint what to do, is there   
   more information needed from the affected system?   
      
   The full bug history is available at https://bugs.debian.org/1118349,   
   which also contains some hardware information.   
      
   Best regards   
   Uwe
