No, this is the command I used:

mount -o loop disk mnt

I think this looks interesting:

EXT3-fs error (device loop0) in ext3_reserve_inode_write: IO failure

The code in ext3_reserve_inode_write() is here:

err = ext3_journal_get_write_access(handle, iloc->bh);
if (err) {
brelse(iloc->bh);
iloc->bh = NULL;
}

Maybe it should do something different here?

But I don't know :-)

Thanks for helping out!
