I've already updated it to the latest based on the suspend2 version. $uname -r 2.6.17-suspend2-r4 $eix xfsprogs Available versions: 2.7.3 2.7.11 2.8.10 Installed: 2.8.10 > > I'm using 2.7.11 on kernel 2.6.16, write performance is reasonably good If not mistaken, the issue, (or barriers if not mistaken) was introduced in the 2.6.17 kernel series. the 2.6.16 series wasn't affected.
