Hi All,

I have a number of PowerEdge 2650/1750/1850/2850 servers running RHEL3u8 and 
OMSA as installed from OMI-SrvAdmin-Dell-Web-LX-450-32-335_A00.tar.gz with 
the new kernel 2.4.21-47.ELsmp.  Following the running of up2date -uf and 
reboot on two of the 2850s I saw this in /var/log/messages:

and the following:

According to other identical machines not upgraded "(Not Available)" should 
read "(Embedded)" and there's a lot of information now "Not Applicable".  So 
for some reason OMSA doesn't seem to recognise/isn't able to access the 
embedded controller fully any more.

Given this all worked pre-kernel update I'm assuming something's gone screwy 
somewhere.  Does anyone have any ideas what else I should be looking for/how 
I might go about fixing things?  I'm not really keen on upgrading to OMSA 
5.0 at the moment with so many other things in flux but a reinstall of 4.5 
is fine.

Any help would be much appreciated.  Thank you.
