Update, I tried doing a git-bisect today. I only tried out kernel 3.18 rc3 which was bad and had the same issue, and then I directly checkout kernel back to 3.8 in which the issue was still occuring. So this means that there was no solution for this bug at all with the exception of catalyst driver? |
Created attachment 143781 [details] dmesg log Hi, When using the radeon DRM module in kernel, putting the system back to sleep and resuming always results in blank screen. It only works if the radeon kernel module is disabled. My System Specs: Asus K55N laptop Processory: AMD A6-4400M APU Graphics: Radeon HD 7520G With windows 7/8, resuming just simply works fine though Regards, Swoorup
