Possible there is soft-lockup issue on that code/module. If you can find something, it's good, if not - it doesn't matter, worst thing, i cannot turn on debugging or smth like this, cause server is heavily loaded.

Are you able to test the latest testing/development kernels? Currently 2.6.16 and 2.6.17-rc2
