Since kernel 3.13, my laptop is unable to boot unless ran with radeon.dpm=0. Worth to note that 3.12 with radeon.dpm=1 works mighty fine. While trying different kernel versions and inspecting syslog, it seems that in all cases the problem starts with the following line: [drm:r600_ring_test] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD) In 3.13-3.15 it results in system restart when the login screen shows up. In 3.16 however, the screen freezes and no restart occurs. The system responds normally when pressing power button and shuts down. Attached is the piece of the syslog and Xorg.0.log when ran with 3.16-rc5. Any help would be greatly appreciated. Thanks. -- You are receiving this mail because: You are watching the assignee of the bug.
