Inginerii de la Canonical au avertizat cu privire la regresiile din urm\u0103toarea actualizare a pachetului cu nucleul 7.0.0-28.28, care va fi livrat utilizatorilor Ubuntu 26.04 \u0219i Ubuntu 24.04.

De exemplu, din cauza regresiei, timpul de execu\u021bie al modelului Stable Diffusion XL (SDXL) utiliz\u00e2nd ComfyUI a fost \u00eent\u00e2rziat de 42 de ori (de la 9 secunde la 388 secunde). <\/p>\n

Apari\u021bia problemei a fost observat\u0103 \u00een actualizarea nucleului Linux 7.0.12, pe baza c\u0103ruia este construit\u0103 versiunea 7.0.0-28.28 a pachetului pentru Ubuntu.

Problema apare \u0219i \u00een pachetele cu nucleul 7.0.12, lansate pentru Fedora, CachyOS \u0219i alte distribu\u021bii Linux. Defectul a fost remediat \u00een versiunea nucleului 7.0.13. Ca solu\u021bie temporar\u0103 pentru a rezolva regresia \u00een ComfyUI, se poate folosi flag-ul «—disable-mmap».
