Installed linux-image-2.6.28-14-generic 2.6.28-14.46 from jaunty-proposed. Ran hang.py, and still obtained a soft lockup. Doesn't seem like the update fixes this problem. So I guess Theodore Tso was right in pointing out above that this might not be the correct fix. (Note that for me 2.6.29-02062902 does not have this lockup problem.)
Also, on one machine, obtaining a crash reliably requires running several hang.py in parallel and modifying the script so that each instance uses its own set of file names.
@martinm1000: Check that `uname -a` reports kernel version 2.6.28-14.
