 Blaaah...
 
 Is there any way to get it to print info about the signal 11, like in
 particular what the program counter was?
 
 Something like this patch might produce a bit more info; but if you
 have to burn a CD to try it, probably better to come up with a more
 complete patch that prints more info. (Such as, for example, a
 complete dump of the trapframe.)
