erreur de noyau: Nouveau problème avec Xorg: nv50cal_space: -16

Question

Exécution de KDE Neon 16.04 LTS x86_64. Après un certain temps de travail, l’affichage commence à se comporter de manière irrégulière et à la traîne, le son s’arrête et lorsque j’essaie d’appuyer sur Alt + F1, la sortie de nouveaux journaux est constamment affichée.

Je réclame ceci à partir du fichier kern.log, tout comme le même résultat obtenu presque à chaque fois:

davdriver-desktop est le nom du système.

Je suis désolé de ne pas donner plus d’informations ou de rechercher une solution, car je n’ai aucune idée de ce que pourrait être le problème. Je peux travailler sans problème pendant des heures et cela se produit parfois, certains jours.

Merci d'avance.

Les erreurs v50cal_space signifient essentiellement que le processeur graphique a été suspendu et que cela se produit lorsque nous sommes à court d'espace dans l'IB pour la soumission de pushbuf. Source: commentaire d'Ilia .

Il y a quelques bogues liés à nv50cal_space qui peuvent être trouvés à bugs.freedesktop.org , en particulier: # 93629 , # 999 et # 100567 (qui sont liés à CTXSW_TIMEOUT).
