Red Hat did a major overhaul of the hwmon branch in the RHEL-5.5 release, backporting many updated drivers from the upstream kernel ~2.6.26 (dating from somewhere around Aug 2008), but obviously even this updated driver branch is now over 3 years old. What hardware sensors do your servers have? Elrepo.org has some updated kernel drivers for commonly used hardware sensors backported from newer upstream kernels (e.g, 2.6.39, 3.x), but some are reliant on the latest distro kernel (built against a later distro kernel) due to kernel ABI changes, so you'd still need to ideally be running an updated installation. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
