dma is turned off

Hi all, Mainboardcontroller: udma100 , Harddisk: udma133 , SuSE9.0 when booting the message : "the dma on your harddrive is turned off. This may really slow down the fsck process" always appears twice I tried different settings in Yast dma on dma100 dma133 - the message is always the same. What is even worse : One of three bootings fails with the msg: Setting up the CMOS clock hda lost interrupt. Exactly the same hardware combination made no dma probs at all with SuSE 8.1 & 8.2. What am I doing wrong / which additional information should I post ? best regards C. Emden
