 Dear Sir/Madam,
 I'm making kernel 2.4.18 support MTD for 8MiB Disk On Chip Mellenium. The
 attachment is the message I got from commanding dmesg. Please help me, I
 can't see the devices /dev/nftla.
 Best regards,
 Pham Cong Thien

That's odd. It seems to be returning an I/O error without saying why. 
Can you enable MTD debugging and also run nftldump on the offending 
DiskOnChip?
