Hi,

I'm no developer, or any technical head, but I think this is a bug in
the Linux kernel, actually I don't even know if it belongs on the MM buglist -
please ignore if it's not.

This is running Linux kernel 2.4.1 on Debian unstable.

While running X, and being root in a terminal, this causes my system to
act funny:
          
        $ cd /
        $ grep -r "0:0.0" *
        grep: dev/kmem: Bad address
        Binary file dev/mem matches
        Binary file dev/core matches
        grep: memory exhausted

This causes my X screen to flicker a lot, and my system generaly
runnning bad, when quitting X - I see that my system uses 180 mb ram (I
have a total of 256 mb ram) on console only, and in top or ps, I can't
see which process which consumes this ram.

I tried it on a friends system, and the exact same behaviour happened.
