Are these fixed now?
I remember that I got similar things with 4.0-current from Monday and
Wednesday.
Both versions should be compiled with maxuser 32.
It was on a PII-400 (Single CPU) and 1G RAM

Now it is running with a 3.1-STABLE from Wednesday (checked out the same
time as the 4.0)

If anybody is interessted in I can check for dumps and debug kernels -
there should be some.
It is not possible to me to run further tests on this hardware.
