carte radeon r9 270 et noyau 4.11

Bonjour
des extraits de log syslog et Xorg.0.log  d un noyau 4.11  avec une radeon R9 270  (le paquet xserver-xorg-video-vesa  et radeon  installé )
le serveur X ne charge meme plus vesa ou autres , KMS prend la main et c'est directement le pilote radeon qui est utilisé.
( un petit xorg.conf basic pour activer DRI3 )
pour ceux que ça intéresse , la prise en charge de la carte en libre est complète
un extrait du syslog sur les DRM pour la video
