Warm reboot not activating firmware updates

[Ben]

I've a Dell PowerEdge 2850 running RHEL 5.3 with OMSA 5.5 with the 
software/hardware/firmware repositories installed in the following manner:

# set up Repos
wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
wget -q -O - http://linux.dell.com/repo/software/latest/bootstrap.cgi | bash
wget -q -O - http://linux.dell.com/repo/firmware/latest/bootstrap.cgi | bash
# install OMSA stuff
yum -y install srvadmin-base srvadmin-storageservices srvadmin-rac4
# install firmware tools
yum -y install firmware-addon-dell
# Tidy up
yum clean all
# Get newest versions of everything required
yum -y update
yum -y install dell_inventory_collector
# install BIOS/firmware updates
yum -y install $(bootstrap_firmware)
update_firmware --yes


However, when run the last command I get this:


[root at simak ~]# update_firmware --yes

[root at simak ~]# shutdown -r now


... which seems to be fine.  Unfortunately nothing happens on reboot and 
those updates have not been applied.

Suggestions, please?
