Okay, my colleague found the right combination of scripts, take the two
attached, run them both a couple of times in parallel for some hours,
and get a stuck ps. This happens both on an old 2.6.29.1 I happened to
still have on one machine as with 2.6.31-rc4. Both of them dual-core
Opterons as the original one. If you want further tracebacks or other
information, let me know.
