/proc/self/mem mapping was intentionally disabled in kernels >= 2.3.27.
DOSEMU (since ages) needs it for
- EMS
- DPMI
- Graphics under X
All those features therefore are broken under 2.3.x.
We know about it, Linus knows about it, and we try to find a working
solution (which isn't that simple due to DOSish messes), but we have no
working patch yet (neither for DOSEMU nor the kernel).
Keep in mind that not having mmap(/proc/self/mem) needs a mayor rewrite
of the DOSEMU mapping code and may need additional alternatives in the
kernel.
So, if you currently need DOSEMU, take a stable kernel (2.0.x, 2.2.x)
