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, totally different controller though. PATA doesn't normally use hard-resets as a means of error recovery - that would mean hitting the RESET line, which I don't think most controllers can do on software command (it usually only gets asserted on power up or hitting the reset button), unlike on SATA where there's a defined way to trigger a COMRESET which is mostly equivalent. Also, that resets both devices on the channel, unlike soft reset which is specific to one device. > > CONFIG_ATA=y > CONFIG_ATA_SFF=y > CONFIG_SATA_NV=y > CONFIG_PATA_AMD=y > >> Why do you have 2.01? > > for the DVD drive? > >> Can you please attach full boot >> log? > > attached. > > Thanks. > Ortwin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
