Hello,

I get easily repeatable problem on ext2fs on -CURRENT (AFAIR, this worked
for earlier versions). I use mke2fs(8) from ports/sysutils/e2fsprogs in
order to create filesystem. Simple how to repeat:

mdconfig -a -t malloc -s 10m
mke2fs /dev/md0
mount /dev/md0 /mnt
cd /mnt
touch 1 2 3 4 5
mkdir 6
mv * 6/

I've obtained trace dump:
