One of my test systems here, running 2.6.25-rc8-git*,
just now crapped out with this in the tail end of dmesg:
[ 20.927780] EXT3-fs error (device sda1): ext3_free_blocks: Freeing blocks not in datazone - block

I had just booted the system, and was simultaneously doing "rm -r" on an old kernel tree
while also doing mirrordir to refressh a different kernel tree from a master copy off NFS.
Not much else to say. e2fsck seems to have recovered things,
and I've repeated the commands successfully after rebooting.
