Well, it seems they are related to my KDE changing the wallpaper : this is
configured to be done every two minutes, and here is my log this morning :

Jan 18 10:07:14 tux kernel: [drm:i915_gem_execbuffer] *ERROR* i915_gem_do_execbuffer returns -512

Jan 18 10:09:14 tux kernel: [drm:i915_gem_execbuffer] *ERROR* i915_gem_do_execbuffer returns -512

Jan 18 10:13:14 tux kernel: [drm:i915_gem_execbuffer] *ERROR* i915_gem_do_execbuffer returns -512

Is this a real error, or should it be a warning, as -512 seems to indicate
an ERESTARTSYS ?

Regards,
Paul
