Jonathan H. Pickard:
: The loopback device in 1.99.7 puts processes who attempt to close it into a : coma (using mount-2.5j). It's possible to use losetup to get status on it : and to attach a file to it, and it's possible to read the data on the other : end of it, but once anything tries to close it, the process freezes and : hangs forever in a state like (after the attached xterm is killed off)
: 9311 ? DW 0:00 (losetup)
You gave a lot of config details, but do not give the commands you use. I just checked again that I can open and read/write and close a file via /dev/loop0 without any problems in 1.99.7.

[Not that I am convinced that the loop code is correct right now. There used to be the possibility of a deadlock (because loop needs another buffer before it can write a buffer to disk), and I have not checked that this problem cannot occur anymore. But this would be a kind of deadlock that kills the system, while you describe a single hanging process.]
