RHEL 6.4 was released on February 21th, 2013. We have tested our packages against this release and identified a couple of issues. Below is a digest of our note sent to the ELRepo mailing list.
1. The current OpenAFS kmod package in elrepo (kmod-openafs-1.6.1-2.el6.elrepo) does not weak-link against the new 6.4 kernel. Jack Neely rebuilt the kmod against the new 6.4 kernel (kmod-openafs-1.6.1-5.el6.elrepo) but that package does not in
turn weak-link against earlier kernels. So users of 6.3 should continue to use the package in the main repository (kmod-openafs-1.6.1-2.el6.elrepo). When you are ready to
update to 6.4, also update kmod-openafs (kmod-openafs-1.6.1-5.el6.elrepo) from the elrepo testing repository at
the same time.
2. Red Hat updated the wireless stack in RHEL 6.4. As a result, there now exists a file level conflict between the kernel-firmware package and the rt2860-firmware and rt2870-firmware packages from elrepo, both providing the same file(s). Users of these devices are advised to uninstall the elrepo drivers and firmware for these devices and revert to the kernel drivers now these
devices are supported by the distro.
