That's surprising, it has been beaten to death in Usenet and on the
mailing lists.

This is most likely an indication of either bad memory, bad cache, or
a broken chipset that doesn't invalidate the cache at busmaster DMA
transfers of a peripheral device.

Try turning cache from write-back to write-through, turning the cache
entirely off, or replacing memory (in this order).
