Missing ipmi kernel modules after upgrade to RHEL 6.4 kernel 2.6.32-358.el6.x86_64

Issue

• Missing ipmiutil kernel modules after upgrade to 2.6.32-358.23.2.el6.x86_64
• We have upgraded one of our system from RHEL 6.3 kernel 2.6.32-279.el6.x86_64 to RHEL 6.4 kernel version 2.6.32-358.23.2.el6.x86_64. Since this upgrade ipmi do not work like before. Also /dev/ipmi0 is not present after system is booted. We have noticed that some ipmi related kernel modules are missing:
