Bug #1481

Updated by tuxillo about 7 years ago

Host panics when root does "ipfw pipe show". 
 
 Doesn't matter if dummynet.ko is loaded via kldload  
  
 or it is loaded with loader. 
 
 Recompilation of dummynet.ko doesn't solve this. 
 
 Dumps availible on http://Sahara.org.ua/~planner/{vmcore,kernel}.{0,1} 
 
 (first dump with release binary, second - with module compiled from git branch  
  
 v2.2.1) 
 
 kgdb output follows:
