help if you disable NCQ with the following command?

Thanks
I had the same idea after I read around the mailing list. (But I was
ignorant
on the way, I actually tried to echo 0 into queue_depth first. Good
thing it doesn't
let me.) Anyway, it has been running without the errors for more than 12
hours
now. I also tried by increasing the disk load, which increases the
chances of the problem
occurring. It has not happened yet.
So yes, disabling NCQ stops the problem from occurring.
Any ideas?
Thanks
