X5DAE Sata drives under Linux

Hi,

I have to get a server with a X5DAE motherboard to run under Linux.
There seem to be timeout problems.
I get (lots of)

hdg: dma_timer_expiry: dma status == 0x21
hdg: error waiting for DMA
hdg: dma timeout retry: status=0x59 { DriveReady SeekComplete DataRequest Error }
hdg: dma timeout retry: error=0x01 { AddrMarkNotFound }, LBAsect=203165360,
high=12, low=1838768, sector=90710360

Does anybody have a server running on this board under Linux?

Many thanks for a hint,
