  • Behobenkernel-rt-0:3.6.11.2-rt33.39.el6rt.src as a component of Red Hat MRG Realtime for RHEL 6 Server v.2redhat_csaf

    This update also fixes multiple bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.6.11.2-rt33, correct these issues, and fix the bugs noted in the Red Hat Enterprise MRG 2 Technical Notes. The system must be rebooted for this update to take effect. Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.
