User-mode Linux kernel port

Thanks.  

I think gcc must have changed its behavior at some point because obviously I 
don't see that problem.

The console has been like that forever.  It's one of those fairly harmless 
things that I haven't bothered chasing down yet.

Which is why I think the problem is in the console driver.

To link the final `linux` executable I need this patch:

Hi,

if I start uml in a gnome-terminal, log in there and issue a command that
generates a lot of output, about everything after line 50 is lost. At that
point I am 'back at the prompt': Sometimes I dont't see the prompt, but I
can type new commands.

Here is sample output:

[buytenh@... buytenh]$ cd /usr
[buytenh@... /usr]$ cd bin
[buytenh@... bin]$ ls
Mail           epstopdf        latex           pfbtops          sun2mime
[lines snipped]
charset        gftopk          metasend        refer            unicode_stop
chattr         gftype          mf              remsync          uniq
checkalias     gindxbib        mft             rename           units
chfn           glibcbug        mimencode       renice           buytenh@... bin]$ 

Note the odd place of the prompt. It does not manifest if I telnet into
the virtual machine. 2.4.0-test6 exhibited the same (buggy) behaviour.

Sounds like some kind of flow control problem?
