dell

hi
we lately purchase few dell servers all of them from Rxxx series couple of R410 and R710

the OS we used on those servers is: CentOS 5.4

we're getting very weird error messages and we lost network connectivity couple of times (restarting the network interface was needed to fix it)

the messages we're getting are:
Message from syslogd@ at Wed Nov 18 12:07:08 2009 ...
servername kernel: Uhhuh. NMI received for unknown reason 20.
Message from syslogd@ at Wed Nov 18 12:07:08 2009 ...
servername kernel: Do you have a strange power saving mode enabled?
Message from syslogd@ at Wed Nov 18 12:07:08 2009 ...
servername kernel: Dazed and confused, but trying to continue

we have never seen those messages in the previous series of dell poweredge servers

do someone here using centOS 5.4 on Rxxx series? did it happen to him too?

maybe you have a suggestion about how to prevent it from happening
