I had not selected DMA. Doing so does not help, but reveals a new choice, namely support for HPT366. Selecting CONFIG_BLK_DEV_HPT366 makes the crash go away. So far about IDE. Marcin wil figure out what went wrong there. I figured out something else, namely that SDDR09 has a built-in scatter-gather read command (several pages on the card to a single memory buffer). Probably also an sg write command, but I have not found it yet. Let me document in public: /* * Read Scatter Gather Command: 3+4n bytes. * byte 0: opcode E7 * byte 2: n * bytes 4i-1,4i,4i+1: page address * byte 4i+2: page count * (i=1..n) */ Finally a question. People tell me that very recently 256MB (2Gb) SmartMedia (NAND flash) cards have appeared. If someone has one of these already, please tell me - I would like to know the device type code.
