Most programs crash under openmosix.

Hi

We run a smallish(18 pc) cluster for AI smulations. At least we are
trying to.

The processes migrate properly but openmosixtest packages and almost all
of our simulations crash after only a few seconds with a kernel oops.
Below is the oops.

We are running openmosix 2.4.30 and openmosix-user 0.3.6-r3 from the
gentoo portage.

Any ideas anyone?

The openmosixtests freeze the machine within 5-10 seconds.

Oops from our program:
