Hi,

Been running a lot of stressful jobs and will let them continue, so far,
no ERROR, WARN or OOPS yet.

3.1-rc4 + the three patches above seem to fix the problems (thus far).

Does anyone know when the bugs were introduced into the kernel, as some/all
of these problems also happened with 3.0.x.

Justin.
