This chipset doesn't have SATA, only PATA. Ahh, ok, it's not sata_nv at all then, it's pata_amd. On the same chip,= =20 totally different controller though. PATA doesn't normally use hard-resets as a means of error recovery -=20 that would mean hitting the RESET line, which I don't think most=20 controllers can do on software command (it usually only gets asserted o= n=20 power up or hitting the reset button), unlike on SATA where there's a=20 defined way to trigger a COMRESET which is mostly equivalent. Also, tha= t=20 resets both devices on the channel, unlike soft reset which is specific= =20 to one device. > > CONFIG_ATA=3Dy > CONFIG_ATA_SFF=3Dy > CONFIG_SATA_NV=3Dy > CONFIG_PATA_AMD=3Dy > >> Why do you have 2.01? > > for the DVD drive? > >> Can you please attach full boot >> log? > > attached. > > Thanks. > Ortwin
