Comment 1 Ernie Petrides 2005-01-27 01:46:31 UTC 
Glen, are you using the correct (ia32e) kernel?  For RHEL3,
you need to be using kernel-2.4.21-27.0.2.EL.ia32e.
Comment 2 Glenn Chu 2005-01-27 01:55:33 UTC 
Did not see the ia32e rpm.   Thanks!
Comment 3 Jim Paradis 2005-01-27 09:58:55 UTC 
Glen, does it work for you now?  If so I'll close this as NOTABUG.
Comment 4 Glenn Chu 2005-01-27 15:19:26 UTC 
Thew ia32e kernel works fine.  Please close.   Thanks again.
