This deals with the fatal DMA errors on my machine. Well done. However, fixing this bug reveals something else. After about 2 hours of streaming on MLB.TV I got this, apparently at random (but this is not a hard error: by disassociating from the AP and reassociating, the rest of the game played fine, and there was no need to load or unload modules): b43-phy0 debug: TX-status contains invalid cookie: 0x0DCE b43-phy0 debug: Out of order TX status report on DMA ring 1.
