Hi, we still think that there is a problem in bttv_risc_packed in computing estimated size. My patch was bad, I see it now, but still don't understand, how it is computed and how it should be: instructions = (bpl * lines) / PAGE_SIZE + lines; instructions += 2; and here it crashes (the first line, the (*rp)) -- actually after while loop. *(rp++)=cpu_to_le32(BT848_RISC_WRITE|BT848_RISC_EOL|todo); *(rp++)=cpu_to_le32(sg_dma_address(sg)); So, Mauro (or somebody from list), have you any idea, what could be wrong?
