Excuse for my english

With the first installation of Ubuntu 14.04, dosemu work fine (foxpro under
dosemu work fine!)
Linux  3.13.0-27-generic #50-Ubuntu

But now, 10 june 2014, after I've update the system
Linux  3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

foxpro under dosemu don't work with this error:
Phar Lap err 35: The 386 chip is currently executing
in virtual 8086 mode under the control of another program.  You must turn
off this other program in order to use 386|DOS-Extender to run in
protected mode

What's the problem?
3.14 linux kernel has dropped the DPMI support for x86_64.
Yours is 3.13.0-29 - my guess is that it had backported
that behaviour from 3.14.
Your previous 3.13.0-27 was likely i686 (32bit), where the
DPMI support is still possible. Or it didn't have the aforementioned

So, to run foxpro, you either need old kernel or 32bit system.
Kernel developers seem to no longer consider dosemu users
as their target audience.
3.15 kernel will probably have a work-around to that problem
because wine was also affected (wine users are regarded much
better, it seems :)
