Created attachment 1231321 [details] dmesg.3.9.5-301.fc19.full trace Description of problem: Impossible to boot if 'nomodeset' is not set. The system hangs during the drm initialisation. Last kernel version working is 3.9.5-301.fc19.i686.PAE Tested all versions after 3.9.5-301.fc19 without success. Version-Release number of selected component (if applicable): 4.8.13-300.fc25.x86_64 How reproducible: My system is Laptop hp dv6 with ATI Mobility Radeon HD 5000 Series If modeset is enabled, when it reach the drm initialization, it hangs forever. . Actual results: Expected results: Additional info: In order to narrow the problem I performed the following steps: -boot in nomodeset -issued command: modprobe radeon modeset=1 -Now system is completely hung. -reboot in nomodeset and get the dmesg trace. See file jctl.fail and fetch pattern '==============' to see what's happens when modeset is enabled by command modprobe. I made the same test with 3.9.5-301.fc19 on the SAME machine: -See file dmesg.3.9.5-301.fc19.full the full dmesg trace. -See file dmesg.3.9.5-301.fc19 that contain only the drm traces.
