Bonjour
J’ai récemment acheter un ordi avec un AMD Athlon Dual-Core QL-60. Et j’ai installé une debian Lenny dessus (64 bit).
Tout fonctionne à merveille et j’en suis très satisfait (j’étais sous ubuntu avant) mais j’ai un problème de detection de ram.
En effet, la commande free me renvoie :
total used free shared buffers cached
Mem: 1760 547 1212 0 13 163
-/+ buffers/cache: 370 1389
Swap: 2910 0 2910
alors que je devrais avoir 2G de ram (d’après ce que j’ai pu voire les 2G sont bien détecté dans le bios). De plus :
# lshw -C

Je devrais donc bien avoir 2G.
J’ai recherché sur le net mais je n’ai rien trouvé de probant (généralement ce genre de problème survenant sur des noyaux 32 bit).
sinon sur les différente info complémentaire que je peux donner :

Si quelqu’un à une idée de ce qui se passe…
Merci d’avance pour vos réponses.
