What could cause a DMA transfer to a page with physical address below 64mb to fail ?
Context: I am using rvmalloc code from bt848 driver in video capture module (km, http://www.sf.net/projects/gatos). The device that does the transfer is AGP videocard (Radeon), transfer from device to main memory.
All transfers to pages with physical addresses below fail consistently.
thanks !
