Cheers, I will give it a try and provide feedback if "it" happens again.

Is it PATA?

Yes. 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.
