Created attachment 114676 [details] dmesg output Hi, I see this message in dmesg after each resume from S3 suspend state. My card is a R9 270x. Prior to kernel 3.19.3, i randomly wasn't able to suspend the machine at all. However, that seems to be fixed now after upgrading to 3.19.3. The only issue remaining is the mentioned error message. I have to admit that the machine works perfectly, Xorg.log shows no errors, everything seems OK, so thank you very much for the important fixes that went into 3.19.3. But I wonder what this error message means. DPM related? I tested the switching of performance levels via debugfs and that seems to work too but maybe not correct??? I attached the dmesg showing the error message, let me know if and how I can help you with some for debug information. Thanks a lot
