DMA geht nur mit Kernel 2.4.18-bf2.4
Hallo,
vielleicht könnt ihbarir ja helfen.
Bei mir funktioniert das Festplatten-DMA nur mit Kernel 2.4.18-bf2.4.
Ich bin mir nicht wirklich sicher, welcher Chip für das DMA zuständig ist,
tippe aber auf den ATI IXP 300 weil damit auch der Sound funktioniert.
Das eigentlich verwunderliche ist, daß DMA mit diesem alten Kernel
funktioniert, obwohl noch gar kein expliziter ATI-Support existiert.
DMA geht mit Kernel 2.4.18-bf2.4 von ftp.de.debian.org und geht nicht mit
2.6.9-1-686 von ftp.de.debian.org.
Auch Versuche den Kernel selber zu kompilieren brachten keine Besserung.
Der Rechner ist übrigens ein Acer Aspire T 310
Mich würde vor allem folgendes Interessieren:
a) welche Kernel-Option in dem 2.4.18-er Kernel bringt den DMA zum laufen
b) vielleicht sieht ja jemand aus lspci was für ein Modul ich für diesen
DMA-Chip brauche.
c) Wurde etwas das im 2.4.18-er Kernel funktionierte wieder ausgebaut? (Es
gab ja etwas später ein extra atiixp modul)
Ich könnte natürlich bei dem 2.4.18-er Kernel bleiben doch leider ist dieser
für meine Soundkarte zu alt.
Danke für die Hilfe!
