Hi Roberto,

With my mimo I see the same bug as the previous version; I get a login 
prompt and I can log in, but if I type "ls" I get lots of messages like 
"FILL RECT 0 464 !!!", and the only thing I can do is power off.

My guess: "ls" produces enough output to make the screen scroll; during 
scrolling the "FILL RECT" message is printk()ed; the printk() needs to 
scroll the screen some more; this causes another "FILL RECT" message - 
recursion ad infinitum.

It's unfortunate that I have to power-off to make this stop.  Is there 
some simple change that can be made so that the driver terminates 
itself forcefully if I unplug the device?


Phil.
