Unfortunately, porting the necessary ext4 patches to 2.6.32 was very difficult, since some of the patches in question had prerequisites that involved fairly massive changes to the quota subsystem. An enterprise distro such as Red Hat could make the backports work, but it wasn't easy, and Red Hat by policy doesn't release its broken out patches, so it's hard for Oracle (and Debian) to profit by the yeoman work done by Eric Sandeen. (Note, by the way, not his fault; blame Red Hat management.) As a result, I would strongly recommend that people use a more modern 3.x kernel. Since Debian Wheezy will be using a 3.2-based kernel, this problem will be addressed for the Debian stable users (hopefully!) soon. Regards, - Ted
