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.
