 Debugging
 
-  oops=panic    Always panic on oopses. Default is to just kill the process,
-                but there is a small probability of deadlocking the machine.
-                This will also cause panics on machine check exceptions.
-                Useful together with panic=30 to trigger a reboot.
-
   kstack=N      Print N words from the kernel stack in oops dumps.
 
   pagefaulttrace  Dump all page faults. Only useful for extreme debugging
