One of my systems runs a squid webcache and has a lot of disk load,
and I've never seen data loss or corruption, all the way up from 2.6.34 to
the latest -git.

(Btw: "noatime" superseeds "nodiratime", you can therefore drop it when
"noatime" is set.)

I would rather guess that you have filesystem / harddisk problems,
but I must admit I've never mounted one of my filesystems with barriers
enabled (I use XFS exclusively).
