 Greetings,\\
 I've noticed that removing inodes with the ext2 driver tends to trigger a
 KDL. Here's how I do it:

 ~>  dd if=/dev/zero bs=1024 count=250000 of=/unnamed\ volume/test\\
 250000+0 records in\\
 250000+0 records out\\
 256000000 bytes (256 MB, 244 MiB) copied, 15,3417 s, 16,7 MB/s\\
 ~> mv /unnamed\ volume/test ./\\
 ~> mv ./test /unnamed\ volume/\\

 The KDL is triggered when I repeat the last two commands a couple of
 times.

 I'm using an ext4 volume formatted with standard options, on hrev52365
 x86_64.
