DMA Polling Bug

The bug fix for the bus adapter's DMA polling feature has not been recompiled on all platforms yet. This document provides instructions on disabling the feature, so that the driver cannot get in a state where it thinks that DMA is active when it is not -- this state prevents the ISR from handling PT/PR/VME interrupts, on the 32-bit bus adapter models.
