How did dosemu crash? Do you see a trace in ~/.dosemu/boot.log?
It might actually be a kernel bug, if dosemu crashes with a plain
"segmentation fault", and if you run "dmesg" after, which says
something like:

--May 22 16:47:47 localhost kernel: note: dosemu.bin[5281] exited with
preempt_count 1

I attempted to fix the issue in the kernel but there was a problem
with the patch -- I'll revisit when I have time.
A workaround is using $_cpu_emu="vm86" or recompiling the kernel with
preemption disabled.
