[Openswan Users] openswan 2.4.4-1 on RHEL4

[Patrick Hartemann]

Hello,

we've modified, recompiled and installed openswan 2.4.4-1 on RHEL4 - 2.6.9-22.0.2.ELsmp - based on SRPM for fedora4.
All seems ok, recompilation and installation, we could modprobe the module ipsec but .... 
the start of ipsec userland freezes the system, and modprobe -r of module generates a panic.
