Al Viro adapeza kuti kernel ya Linux yama s390x sinali kugwira ntchito bwino al pangani zosintha patebulo lamasamba pazigawo za maso zomwe zimagwiritsa ntchito njira yachiwiri ya adilesi. Wowukira m'deralo atha kugwiritsa ntchito izi kuyambitsa kukana ntchito (dongosolo hang) kapena kupanga nambala yokhayokha.

Kuti tikhazikitse zigamba izi ndikudziteteza ku zolephera zonsezi, ingotsegulirani pulogalamu yamankhwala athu (kapena Pulogalamu Yowonjezera Mapulogalamu) ndikuyika mapaketi atsopano omwe atiyembekezere kale. Kuti zosinthazo zichitike, padzafunika kuyambitsanso makina ogwiritsira ntchito, pokhapokha titatsegula LivePatch yomwe imapezeka ku Ubuntu 20.04.
