Information on how to modify your kernel so that you can force
a crash from a user application can be found in the following
FAQ:

  http://oss.sgi.com/projects/lkcd/faq.html

It contains an example of how you to modify the sys_setpriority()
function so that, it causes either a panic or a SEGV trap. There is
also a sample program that calls setpriority() to initiate the dump.
