Due to an obvious bug in the latest 2.4 kernels, dosemu can
easily cause the system to panic. Generally it only oopses,
but maybe with preempt patch it reboots instead.
Try the attached fix.
No guarantee that it will fix your particular problem (I've
seen only oopses, lots of them, but no reboots) but it might
fix the segfaults (but not page faults) on startup and some
other crap people lately observed with dosemu.
