I would search for kernel issues for your model server and the 6.5 kernels, as I think the issue is with some hardware drivers and not related to the other userland packages (unless you happen to be using a kmod somewhere). That being said, you should always try to stay current with all updates to maximize the chances that everything works together .. and Laurent is absolutely correct, the only tested 'upstream' solution (other than their EUS?AUS solutions) is what he said, which is: "Before applying this update, make sure all previously released errata relevant to your system have been applied." As far as what kernel is designed for which release ... every point release (minor version) will have its own kernel branch associated with it, you can see this at http://vault.centos.org/ For example, 6.0 has: kernel-2.6.32-71.el6 All the other 6.0 kernels are kernel-2.6.32-71.x.y.el6 .. ie, kernel-2.6.32-71.7.1.el6, kernel-2.6.32-71.14.1, kernel-2.6.32-71.18.1.el6, kernel-2.6.32-71.18.2, etc. The following is a breakdown of what each starts with: 6.0: kernel-2.6.32-71 6.1: kernel-2.6.32-131 6.2: kernel-2.6.32-220 6.3: kernel-2.6.32-279 6.4: kernel-2.6.32-358 6.5: kernel-2.6.32-431 6.6: kernel-2.6.32-504 Thanks, Johnny Hughes
