Panic lanuching dosbox

[Andrea Venturoli]

Hello.
I'm running 6.1p10/i386 on an Athlon XP box.
Each time I run dosbox or any other apps that goes fullscreen from X11 
my system reboots.
I tried running dosbox in single user mode and I got the following dump.
However I'm not so expert in kernel to make something useful out of it. 
Can anyone help?

The only thing I understand is that it seems to have something to do 
with USB, but I can't explain why. Maybe because I've got USB keyboard 
and mouse?

  bye & Thanks
	av.
