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 Radeon AIW AGP, transfer from device to main memory. All transfers to pages with physical addresses below 0x4000000 fail consistently. thanks !
