Description of problem:
Installed RHEL5-B2 64-bit(kernel-2.6.18-1.2747.el5) on PE1800 which has Intel 
LOM.
When we stop the network service and try to unload the e1000 module,the module 
is not unloaded and it is still seen in the lsmod output.This issue is seen 
even with tg3 driver.
When we try to unload the e1000 module,we get the below message on the console :

Version-Release number of selected component (if applicable):
RHEL5-B2 64-bit(kernel-2.6.18-1.2747.el5)

Networking issue. Adding to 5.0 wish list to obtain ACKS.
Comment 3 RHEL Program Management 2006-12-13 19:21:24 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 4 Samuel Benjamin 2006-12-14 19:02:34 UTC 
Dell wants to confirm with RH network engineering if this is a known issue or
working as designed. Is there is any way to work around it then they will like
to know it.
Comment 5 Larry Troan 2007-01-03 19:33:49 UTC 
Per Engineering, this was a bug in initscripts where depending on whether
SELinux was active or not, a module could be reinserted after being removed via
rmmod. 

Reference bug 211474 'setenforce 0' will cause the modules to be re-loaded
automatically after remove by 'rmmod' which was fixed in
initscripts-8.45.10.EL-1.1. Fix was confirmed by another partner on 2006-12-11
and bug 211474 was CLOSED=CURRENTRELEASE.

*** This bug has been marked as a duplicate of 211474 ***
Comment 6 Amit Bhutani 2007-01-10 18:00:00 UTC 
Since we do not have access to bug 211474, we would have to test this ourselves
before we deem this fixed. 

Bili- Would you like to quickly regress and report results here ??
Comment 7 John A. Hull 2007-01-10 20:09:56 UTC 
I confirmed that this is resolved in RC snapshot 5.
