[rhn-users] RedHat AS4 (w/SE Linux) Update 1

[Robin]

All,

Somehow, we've got RedHat AS3 which at 3rd and 4th upgrades still 
experience panic issues every week or so.
bugzilla.redhat.com pointed out it's auditd and perhaps some other 
issues. I've setup netdumps, etc., and seem to point out to auditd.
I've disabled auditd on production machines running RedHat AS3. RedHat 
AS3 (Update 4) has some other issues, in addition of auditd.
Since there are several admins personnels, I've to discuss w/ them  for 
the updates so as to get all the systems to the latest 5th update.
It's a bit annoying to see kernel panic that often. An update seems 
necessary to me.

I used Slack at home. I've compiled many versions of kernel. I've tried 
out 3rd party patches at home. All work fine w/ IDE, SCSI, network card, 
etc.
None of them panics like RedHat AS.

The work environment decides to go w/ RedHat (for the advertised support 
from IBM, etc.).

On a test machine, I've just installed RedHAt AS4 (w/ SELinux) Update 1 
on a dual CPU machine.
It detected both CPUs, but somehow, it failed to use both CPUs. I've 
searched bugzilla on RedHat AS4 on the matter and didn't find anything 
(perhaps I need to search deeper?).
