btw, there are bugs with it.  Starting several processes with init or
even telnetd will expose the bug.
David and I haven't been able to reproduce this on the Walnut or the
EP405.  What sort of machine are you using, what processor, how much
RAM, and what distro are you using?

Paul.
I run MVL (of course) on a walnut with 32MB of RAM.  What is your
environment?  btw, MVL uses soft-float in glibc not floating point
emulation in the kernel.
I've tried it both on a Walnut (PVR 401100c4) with 128MB of RAM, root
filesystem on an IDE disk attached to a Promis PCI IDE controller and
on an EP405PC board (PVR 40110145) with 64MB of RAM with NFS root.  In
both cases userland is Debian/sid running with kernel math emulation.
