Unfortunately if the GPU is unhappy on resume, that means that the console also hangs. Specifically it was commit ecf24de071f4f6cea79ecef5d990794df5875ee1. Could you test a few kernels to see whether it's the same issue you're seeing? e.g. does 3.14 work while 3.15 fails? If so, can you do a bisect to confirm (and if not, also do a bisect to figure out what broke it). git bisect start v3.16 v3.13 -- drivers/gpu/drm/nouveau should cover the whole range you mentioned (3.13 = good, 3.16 = bad). Separately, could you attach a full dmesg after boot? That should answer a number of basic questions about some of your setup's specifics. Additionally, how is your monitor(s) connected?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
