SubjectVIA & UDMA / Kernel 2.2.17
Hi there ...

I have the 2.2.17 Kernel with the VIA
Chipset Support. My BIOS says that my HD
(Samsung) is in UDMA Mode 4. A friend of
mine told me that I can increase my
disk performance a little if I use DMA.

hdparm -d 1 /dev/hda

But I will get the following errors whenever
I run hdparm -tT /dev/hda :

Sep 25 10:07:02 cello kernel: hda: DMA disabled

Whats wrong there?
