EXT3-fs error (device loop0): ext3_free_blocks: Freeing blocks not in
datazone - block = 524288, count = 1
EXT3-fs error (device loop0) in ext3_free_blocks_sb: IO failure
BUG: unable to handle kernel NULL pointer dereference at 0000000c

the programmer was not looking is intellectually dishonest as it
disguises that the error is the programmer's own creation."
