Los ingenieros de Canonical han advertido sobre la presencia de regresiones en la pr\u00f3xima actualizaci\u00f3n del paquete del n\u00facleo 7.0.0-28.28, que ser\u00e1 entregado a los usuarios de Ubuntu 26.04 y Ubuntu 24.04. La regresi\u00f3n se manifiesta al utilizar el controlador amdgpu y provoca una disminuci\u00f3n significativa en el rendimiento de algunas aplicaciones que utilizan la pila AMD ROCm. Por ejemplo, debido a la regresi\u00f3n, el tiempo de ejecuci\u00f3n del modelo Stable Diffusion XL (SDXL) usando ComfyUI se ralentiz\u00f3 42 veces (de 9 segundos a 388 segundos). <\/p>\n

La aparici\u00f3n del problema se ha se\u00f1alado en la actualizaci\u00f3n del n\u00facleo de Linux 7.0.12, sobre la cual se basa la versi\u00f3n 7.0.0-28.28 del paquete del n\u00facleo para Ubuntu. Se destaca que la actualizaci\u00f3n preparada contiene correcciones de importantes vulnerabilidades y que Canonical no puede posponerla debido a la regresi\u00f3n se\u00f1alada. Por lo tanto, se ha decidido lanzarla tal como est\u00e1, siendo la regresi\u00f3n corregida en la pr\u00f3xima actualizaci\u00f3n de mantenimiento. Los usuarios para quienes la regresi\u00f3n se\u00f1alada es m\u00e1s cr\u00edtica que la correcci\u00f3n de vulnerabilidades pueden optar por no actualizar a la versi\u00f3n 7.0.0-28.28 y esperar la siguiente actualizaci\u00f3n. <\/p>\n

El problema tambi\u00e9n se manifiesta en los paquetes con el n\u00facleo 7.0.12, lanzados para Fedora, CachyOS y otras distribuciones de Linux. La deficiencia ha sido corregida en la versi\u00f3n del n\u00facleo 7.0.13. Como soluci\u00f3n alternativa para evitar el regresi\u00f3n en ComfyUI, se puede utilizar la bandera «—disable-mmap».
