Subject: DMA unuseable on Compaq presario 1260
Date: Sat, 1 Nov 2003 17:26:23 -0600	[thread overview]
Message-ID: <200311011726.23301.ratcheson@earthlink.net> (raw)

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?

TIA,
Richard
