Hello Chris, hello Joel,

my network was running hot all night and the system is still alive 
and kicking. Your patch works fine and definitely cures the problem 
for all the "small" M68K processors. 

Joel, can you add the patch to the source tree? 

I think all M68k rtems users should be aware of that bug (and the 
patch), because it might lead to deadline misses concerning interrupt 
response time in rare conditions.
