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

Yes. This chipset doesn't have SATA, only PATA.

CONFIG_ATA=y
CONFIG_ATA_SFF=y
CONFIG_SATA_NV=y
CONFIG_PATA_AMD=y

for the DVD drive?

attached.

Thanks.

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.

Yeah, if it's pata_amd and SRST isn't recovering the device, there
isn't much else to do. :-(

Thanks.

Alright, no worries. I'll try to address the problem from the hardware side
then: cables, drives, etc.

Thanks.

PATA soft reset affects both devices too. Unless you mean ATAPI Device
Reset command.
