I would really appreciate some feedback on this. It's a RH 6.0 distro
with the RH 6.1 kernel srpms rebuilt and running. Raid array made with
mkraid from raidtools 08241999.

I *really* need suggestions here. This is a system which is supposed to
go production on Monday and I'm not feeling too good about this.

Here's some more output:
