J'ai des freezes réguliers de 30 secondes :
dmesg :
J'en ai plein, régulièrement comme ça, qui me freezent le PC pendant 30 secondes :/ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

Ces freezes sont assez bizarres :
En général la musique qui se coupe prévient d'un freeze. Dans ces cas là, si par exemple j'ouvre un terminal, je peux taper dedans, mais il suffit que je presse "tab" pour qu'il freeze à son tour... il faut attendre 30 secondes pour avoir de nouveau la main.
Niveau performance c'est un PC neuf (Samsung R55 XEH 2300) acheté il y a 3 mois. Conky ne m'indique d'ailleurs, pendant un freeze (car tout continu de tourner plus ou moins si on ne les brusque pas) aucun pic du processeur, de température ou de saturation de la RAM... rien de spécial... c'est comme si rien ne s'était passé.
J'ai tenté de booter avec noacpi et nolacpi mais ça n'a rien changé, dommage.
D'après les messages ça proviendrait de mon disque dur S-ATA. D'après la doc de mon PC j'ai un disque dur S-ATA (d'ailleurs j'ai un périphérique /dev/sda) pourtant, voici ce que renvoi lspci :
