[Bug 494476] Re: "Smbd", "kjournald2" and "rsync" blocked for more than 120 seconds while using ext4.

[Lars]

Hi Tom,

yes I haven't had this »freezes« with noop.

With our setup it was reproducable. After some (3-4) hours of heavy io-
load from the hdds our process gets blocked for more than 120s and then
it stopps itself because it couldn't write to the tape drive any more.

With noop the backup (actual two of them in parallel) has run 13 hour
without any strange log entry.

Lars
