In my design I use a st16c2550 device from Exar (a 16550A like). One of
his interrupt line is connected to IRQ7 of the 5206e. 
My problems occur when i use this device : the kernel freeze and 
enter in a infinit loop after a variable time of use. 

So my questions are :

 - Does the driver (serial.c) for the 16550 of the uClinux distribution 
for ColdFire work correctly ? 

- Is it possible to use the interruptions of level 7 without affecting
the operation of the kernel ?

Thank in advance.
