Ext4 corruption that will not go away

[Ed Tomlinson]

Hi,

I am running 2.6.31-rc8+ and have ext4 corruption that will not go away.

My root fs is ext4 on sdb3.  I have moved the directory with corruption into lost+found and booted to a rescuse
system (arch linux) and run fsck.ext4 on the filesystem, which then reports its clean...  Booting back into my
gentoo system and attempting to remove the xx directory from lost+found gives:

[  172.408799] EXT4-fs error (device sdb3): ext4_ext_check_inode: bad header/extent in inode #706801: invalid magic - magic 0, entries 0, max 0(0), depth 0(0)                                                                                                
[  172.429410] EXT4-fs error (device sdb3): ext4_ext_check_inode: bad header/extent in inode #706801: invalid magic - magic 0, entries 0, max 0(0), depth 0(0)                                                                                                
[  172.449920] EXT4-fs error (device sdb3): ext4_ext_check_inode: bad header/extent in inode #706801: invalid magic - magic 0, entries 0, max 0(0), depth 0(0)

The above is repeatable.

How can I _really_ clean this fs?  What info is needed to help the process?

TIA,
Ed Tomlinson
