Perhaps because for non-redhat users, 2.4 is considered "old hat" and
they can't understand why Redhat is *still* using 2.4 (?!)
RHEL is using a 2.4 kernel because that is what they chose to make stable. You are on a RedHat mailing list discussing a RedHat product.  Thousands of customers running Oracle on RHEL 3 AS are quite happy that RedHat is using a 2.4.21 kernel (as an example).  They are also happy that RedHat is making GFS 6.0 available for the RHEL 3 product line.

Urm, I guess I don't "have" to use 2.6, but it would be "really" painful
for me not to use 2.6 .. for way more reasons than I want to list here.
Use whatever you want ... only don't expect software that someone says is unstable to be stable.  IF you want a stable GFS from RedHat ... use RHEL and GFS 6.  If you want to use another distro and another GFS ... great ... just don't complain that it is not stable.

Sure, thought you should appreciate that for people who've been off 2.4
and in production on 2.6 for a long time, comments like "you should be
using 2.4" are a little redundant.
Again ... you are the person who chooses what technology you deploy ... but RedHat is going to put out stable products for their supported RHEL.  If you can make it work on a different distro with a different kernel, great.
