Hi David, I don't know if you follow the linux-ide mailing list, but there's been a ton of work done on SATA error handling, the sata_nv driver, and NCQ support between 2.6.16 and 2.6.25.
I have been paying attention, looking to find SATA Port Multiplier support the moment it's ready. I don't think it's in Hardy kernel BTW. I'm curious to know more about your issue. Are you setting Write Cache off? That triggers it for me since it doesn't take much write load to cause multiple outstanding commands that way. What filesystem are you using, do you use device-mapper, anything else about your setup, like smartd, mdadm daemon, that might be accessing the drives? My impression of Hardy (which is supposed to be a long-term release - LTS) is that it's going out on schedule, no matter how many unresolved issues... sadly it feels like windows a bit. I'm a bit upset they deferred this patch, yet managed to find the time to introduce other kernel changes that disabled a number of sound cards. so a word to the wise, test like crazy, 2.6 series is undergoing a ton of changes upstream as well. buyer beware. As for kernel command line, I haven't tried these, but you can turn off ADMA mode, as well as NCQ. But the real fix is the patch I mentioned in the Ubuntu ticket. It gives the exact GIT commit ID, as well as a reference to the mailing list post about it. You can rebuild your kernel from source + that patch for a fix. I may have to use the Hardy kernel source + that patch until they release the fix, or go back to Gutsy kernel and patch in the dme1737 hardware monitor driver.
