Hi,
Randomly I might get a bug on an AMD E1-1200 : screen won't turn on and when X is supposed to start I get a lot of these: [ 307.718332] radeon 0000:00:01.0: couldn't schedule ib [ 307.718348] [drm:radeon_cs_ib_chunk] *ERROR* Failed to schedule IB ! [ 307.719063] radeon 0000:00:01.0: couldn't schedule ib [ 307.719075] [drm:radeon_cs_ib_chunk] *ERROR* Failed to schedule IB ! [ 307.734461] radeon 0000:00:01.0: couldn't schedule ib [ 307.734476] [drm:radeon_cs_ib_chunk] *ERROR* Failed to schedule IB !

They stop once X is stopped.
