DMA unuseable on Compaq presario 1260
Date: Sat Nov 01 2003 - 18:27:09 EST
I have a Compaq laptop with the OPTI 82C825 IDE chipset. Up until 2.4.20 the
DMA worked fine. Beginning with 2.4.20 i get the message HDIO_SET_DMA
FAILED: Operation not permitted each time I try to enable DMA.
Distro is SuSE 9.0 current kenel is 2.4..21-99. default
If I go back to 2.4.19 dma works fine.
I have RTFM, maillists, etc. since April and all I can find are references to
other systems with same problem and on in which Alan Cox says he changed
something which broke the Toshiba. But no fixes for my machine. I waited
patiently for the 9.0 upgrade hoping it would be fixed but no joy.
Is there an easy fix or do I need to compile a special kernel for this one?
