Alors, sur notre contrôleur raid matériel, un lspci donne :

RAID bus controller: Intel Corporation 82801 SATA Controller [RAID mode]
(rev 05)

Et dmesg donne :

D'après lspci le contrôleur est supporté par le driver noyau ahci, qui
pour sa part a l'air satisfait :

Ça vous parle ? Du coup, pourquoi l'installeur debian butte ?

Merci de vos lumières.

PS : le copain a pu obtenir ces infos en bootant un truc qui fait serveur
et permet de voir les logs et le matos (je ne connais pas le nom de
l'outil)...
