Hi,
	What is the chipset on your motherboard? It looks like u only have
experimental UDMA support for ur particular chipset. I too get similar
problems once in a while on my Ali M1541 chipset for which the driver is
unstable but usable.

	U can disable bus mastering permanently by running 
	hdparm -d0(?) /dev/hdxx. 

	Please do check the man pages for the exact parameter. Also, a news
group search might also be fruitful.
