How to force a Kernel Panic? (on RHEL 4.0)

[Anu Matthew]

I essentially wanted to test RHEL 4.0 netdump clients. Forcing an 
incorrect parameter as a boot option will indeed cause a panic, but 
would not serve my purpose.

netdump client is usually started in runlevels 2,3 and later, and panic 
from forcing a wrong parameter would happen way before it would enter 
into runlevels.
