#77 Kernel panic after directory renaming

[Valentin]

I disabled dir_index on the ext3 drive, run ext2fsx and created a directory on the newly mounted drive. I tried to rename the directory which resulted in a kernel panic. I repeated the above after reinstallation of ext2fsx, same behaviour. Below my panic.log and parts of the system.log just before the crash.
