Les ing\u00e9nieurs de Canonical ont averti de l'existence de r\u00e9gressions dans la mise \u00e0 jour \u00e0 venir du package du noyau 7.0.0-28.28, qui sera livr\u00e9e aux utilisateurs d'Ubuntu 26.04 et d'Ubuntu 24.04. La r\u00e9gression se manifeste lors de l'utilisation du pilote amdgpu et entra\u00eene une diminution significative des performances de certaines applications utilisant la pile AMD ROCm. Par exemple, en raison de la r\u00e9gression, le temps d'ex\u00e9cution du mod\u00e8le Stable Diffusion XL (SDXL) utilisant ComfyUI a \u00e9t\u00e9 r\u00e9duit de 42 fois (de 9 secondes \u00e0 388 secondes). <\/p>\n

Le probl\u00e8me a \u00e9t\u00e9 signal\u00e9 dans la mise \u00e0 jour du noyau Linux 7.0.12, sur laquelle est bas\u00e9e la version 7.0.0-28.28 du package du noyau pour Ubuntu. Il est \u00e0 noter que la mise \u00e0 jour pr\u00e9par\u00e9e contient des correctifs pour des vuln\u00e9rabilit\u00e9s majeures, et la soci\u00e9t\u00e9 Canonical ne peut pas la retarder en raison de la r\u00e9gression signal\u00e9e, il a donc \u00e9t\u00e9 d\u00e9cid\u00e9 de la publier telle quelle, et de corriger la r\u00e9gression dans la prochaine mise \u00e0 jour correctionnelle. Les utilisateurs pour qui la r\u00e9gression signal\u00e9e est plus critique que la correction des vuln\u00e9rabilit\u00e9s peuvent choisir de ne pas passer \u00e0 la version 7.0.0-28.28 et d'attendre la prochaine mise \u00e0 jour. <\/p>\n

Le probl\u00e8me se manifeste \u00e9galement dans les paquets avec le noyau 7.0.12, publi\u00e9s pour Fedora, CachyOS et d'autres distributions Linux. Le d\u00e9faut a \u00e9t\u00e9 corrig\u00e9 dans la version du noyau 7.0.13. En tant que solution de repli pour r\u00e9soudre la r\u00e9gression dans ComfyUI, vous pouvez utiliser le drapeau «—disable-mmap».
