Ngenkathi kudingidwa izindlela zokusebenza zamaphrosesa e-x86 angawusekeli umyalo we-"cmpxchg8b", uLinus Torvalds uthe kungase kube isikhathi sokwenza ukuba khona kwalo myalelo kube yimpoqo ukuze i-kernel isebenze futhi yehlise ukusekelwa kwama-i486 processors angasekeli "cmpxchg8b" esikhundleni sokuzama ukulingisa ukusebenza kwalo myalelo kumaphrosesa okungasasetshenziswa muntu. Njengamanje, cishe konke ukusatshalaliswa kwe-Linux okuqhubeka nokusekela izinhlelo ze-32-bit x86 kushintshele ekwakheni i-kernel ngenketho ye-X86_PAE, edinga ukwesekwa kwe-"cmpxchg8b".
Ngokusho kukaLinus, ngokombono wokusekelwa kwe-kernel, ama-processor we-i486 alahlekelwe ukuhambisana kwawo, naphezu kokuthi asatholakala ekuphileni kwansuku zonke. Esikhathini esithile, abacubungulayo baba imibukiso yasemnyuziyamu futhi kungenzeka ukuthi badlule βngeminyuziyamuβ cores. Abasebenzisi abasenezinhlelo ezinama-i486 processors bazokwazi ukusebenzisa ukukhishwa kwe-LTS kernel, okuzosekelwa iminyaka eminingi ezayo.
Ukumiswa kokusekelwa kwama-i486s akudala ngeke kuthinte ama-Intel ashumekiwe ama-Quark processors, okuthi, nakuba eyingxenye yekilasi le-i486, afake imiyalo eyengeziwe enezici zesizukulwane se-Pentium, okuhlanganisa ne-βcmpxchg8bβ. Okufanayo kusebenza kuma-Vortex86DX processors. Ukusekelwa kwama-i386 processors kwanqanyulwa ku-kernel eminyakeni eyi-10 edlule.
