FYI, the schematics are openly available. http://www.freescale.com/files/32bit/hardware_tools/schematics/MPC8349EMITXESCH.pdf?WT_TYPE=Schematics&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Downloads > If it is wired using 8 bit data bus line, > without another patch, data transfer can't be done. It is wired that way: LBD[7:0] D[0:7] LBD[15:8] D[8:15] LBA[30..28] A[0..2] I.e. 16 bits for data. > Looking at logs Sam Sparks provided (without irq): > > ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) > > it seems data transfer failed. Well, w/o IRQs everything is OK. I think it's just a bogus message after the interrupt issues.
