Tichiri kukurukura nezve maworkaround e x86 processors asingatsigire "cmpxchg8b" rairo, Linus Torvalds akataura kuti ingangove nguva yekuita kuti kuvepo kwekuraira uku kusungirwe kuti kernel ishande uye kudonhedza rutsigiro rwei486 processors isingatsigire "cmpxchg8b" pachinzvimbo chekuyedza kutevedzera mashandiro eiri rairo pane ma processor ayo hapana anoshandisa zvakare. Parizvino, dzinenge dzese kugoverwa kweLinux dzinoramba dzichitsigira 32-bit x86 masisitimu achinja kuvaka kernel neX86_PAE sarudzo, inoda "cmpxchg8b" rutsigiro.
Sekureva kwaLinus, kubva pakuona kwerutsigiro rwekernel, i486 processors vakarasikirwa nekukosha kwavo, kunyangwe ivo vachiri kuwanikwa muhupenyu hwezuva nezuva. Pane imwe nguva, ma processor anove mamuseum ekuratidzira uye zvinokwanisika kuti vapfuure ne "museum" cores. Vashandisi vachine masisitimu ane i486 processors vachakwanisa kushandisa LTS kernel kuburitswa, iyo inotsigirwa kwemakore mazhinji ari kuuya.
Kumira kwerutsigiro rwekirasi i486s hakuzokanganisa Intel's yakamisikidzwa Quark processors, iyo, kunyangwe ivo vari vekirasi i486, inosanganisira yakawedzera mirairo yechizvarwa chePentium, kusanganisira "cmpxchg8b". Izvo zvinoshandawo kune Vortex86DX processors. Tsigiro yei386 processors yakamiswa mukernel makore gumi apfuura.
