From time to time this nVidia SATA controller chokes on a FLUSH CACHE.

1. why does the kernel not try to HARD reset the link?
2. it would be nice to have the possibility to manually force a (hard) reset or to re-initialize the device. Other than rebooting I mean :-)

Thanks.

Kernel is basically a 2.6.32.8 with a cherry picked fix:

1. why does the kernel not try to HARD reset the link?

Because hardreset sometimes brings the link completely offline on sata_nv's. Hardreset on sata_nv controllers is quite fragile.

Maybe we can use hardreset as the last resort before ditching the device. Something like the following. Can you please try it and post the kernel log? Thanks.

Meh, it won't work. It's failing softreset so we should be checking reset try counts. I'll try to write up something tomorrow.

Thanks.

I am happy to try patches. The problem shows up maybe once a month only, however. Interestingly it only occurs on ata2 with a IBM hdd, never on the first channel with a maxtor. I can also try and attach the dvd on the first channel and see if that makes any difference.

Problems like this definitely can depend on the specific drive.

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.

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
