Hi,

Currently in io_32.h page_to_phys is defined as:

#define page_to_phys(page)	(((page) - mem_map) << PAGE_SHIFT)

Should it not be:

#define page_to_phys(page)	((((page) - mem_map) << PAGE_SHIFT) + phys_base)

or perhaps:

#define page_to_phys(page)	((dma_addr_t)page_to_pfn(page) << PAGE_SHIFT)

Best regards,
Kristoffer Glembo
