The configuration on which the filesystem corruption was observed
is a Tyan Tomcat III board + WD 2.2GB drive; that motherboard is
using the 430HX chipset, which pre-dates Ultra-DMA and doesn't
support CRC check.

If it's a WD Caviar of some sort, I see these corruptions too. Every
machine I have ever had the unfortunate luck to have a WD Caviar IDE
disk in, gave me random corruptions with DMA enabled over time.

I think the real solution is a "DMA black list" for certain IDE drive
types and manufacturers.
