Description Doug Chapman 2007-02-08 15:37:23 EST
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):

http://marc.theaimsgroup.com/?l=linux-kernel&m=112311594619258&w=2

I am working on porting that patch to current RHEL4 source.

Version-Release number of selected component (if applicable):
RHEL4 (all)


How reproducible:
100% on ia64 montecito hardware

Steps to Reproduce:
1. modprobe -v lockd nlm_udpport=4001 nlm_tcpport=4001
2.
3.
  
Actual results:
panic!

Expected results:
