Hmm, this happens on standard Fedora kernel too. 6.0.8. ----- Mail original ----- De: "Yann COLLETTE" <ycollette.nospam@xxxxxxx> À: linux-rt-users@xxxxxxxxxxxxxxx Envoyé: Vendredi 18 Novembre 2022 11:33:02 Objet: Kernel crash with AMD proc and Radeon graphic card Hello, I noticed a problem while using kernel-rt on post 6.0 kernel (maybe it happened before, but I am not sure). I managed to get a stack trace for this problem. The crash was triggered while starting playing a video.
