Description of problem:
Loading some modules with parameters can cause a panic on RHEL4. This is easily
reproduced on ia64 montecito hardware (although likely possible on other
hardware as well).
This was fixed upstream some time ago (2.6.12):
I am working on porting that patch to current RHEL4 source.
Version-Release number of selected component (if applicable):
100% on ia64 montecito hardware
Steps to Reproduce:
1. modprobe -v lockd nlm_udpport=4001 nlm_tcpport=4001
