--- Comment #13 from Luzipher luziphermcleod@yahoo.ie --- The last patch helps, no more messages and the computer doesn't hang completely for several seconds (I wouldn't exactly say that's harmless ;-) ). Thanks for the fix !
I detected a few different error messages when checking dmesg: [drm:radeon_atom_get_leakage_vddc_based_on_leakage_params] *ERROR* Unknown table version 3, 1
Do those warrant a new bugreport ?
