Geoff,
The line number reported seems to be a "red herring" as well, there isn't an
actual BUG_ON assert at line 149 in ...asm-i386/dma-mapping.h, what is there
is...

static inline int
dma_set_mask(struct device *dev, u64 mask)
{
 --->       if(!dev->dma_mask || !dma_supported(dev, mask))
                return -EIO;

        *dev->dma_mask = mask;

        return 0;
}

there aren't any BUG_ONs in dma_supported() either, but they are sprinkled
through several functions in the module, should I try disabling  ALL of
them?
