Ingenj\u00f6rer fr\u00e5n Canonical har varnat f\u00f6r regressionsproblem i den kommande uppdateringen av k\u00e4rnpaketet 7.0.0-28.28, som kommer att levereras till anv\u00e4ndare av Ubuntu 26.04 och Ubuntu 24.04. Regressionen visar sig vid anv\u00e4ndning av drivrutinen amdgpu och leder till en avsev\u00e4rd nedg\u00e5ng i prestanda f\u00f6r vissa applikationer som anv\u00e4nder AMD ROCm-stacken. Till exempel har exekveringstiden f\u00f6r modellen Stable Diffusion XL (SDXL) med ComfyUI saktat ner med 42 g\u00e5nger (fr\u00e5n 9 sekunder till 388 sekunder). <\/p>\n

Problemet har noterats i Linux-k\u00e4rnuppdateringen 7.0.12, p\u00e5 vilken version 7.0.0-28.28 av k\u00e4rnpaketet f\u00f6r Ubuntu \u00e4r baserad. Det rapporteras att den f\u00f6rberedda uppdateringen inneh\u00e5ller \u00e5tg\u00e4rder mot viktiga s\u00e5rbarheter och att Canonical inte kan skjuta upp den p\u00e5 grund av den noterade regressionsen, s\u00e5 beslutet har fattats att ge ut den som den \u00e4r, och regressionsproblemen kommer att \u00e5tg\u00e4rdas i n\u00e4sta korrigerande uppdatering. Anv\u00e4ndare f\u00f6r vilka den noterade regressionen \u00e4r mer kritisk \u00e4n \u00e5tg\u00e4rdandet av s\u00e5rbarheterna kan v\u00e4lja att inte g\u00e5 \u00f6ver till version 7.0.0-28.28 och v\u00e4nta p\u00e5 n\u00e4sta uppdatering. <\/p>\n

Problemet uppst\u00e5r \u00e4ven i paket med k\u00e4rna 7.0.12, som har sl\u00e4ppts f\u00f6r Fedora, CachyOS och andra Linux-distributioner. Felet har \u00e5tg\u00e4rdats i k\u00e4rnversion 7.0.13. Som en tempor\u00e4r l\u00f6sning f\u00f6r att l\u00f6sa regressionen i ComfyUI kan flaggan «—disable-mmap» anv\u00e4ndas.
