The kernel lt packages are built from the sources available from The Linux Kernel Archives, just like the kernel ml packages. The difference is that kernel lt is based on a long term support branch and kernel ml is based on the mainline stable branch. The kernel configuration is based upon the default RHEL configuration with added functionality enabled as appropriate. The packages are intentionally named kernel lt so as not to conflict with the RHEL kernels and, as such, they may be installed and updated alongside the regular kernel. To install kernel lt you will need elrepo release 5 3. EL5 or elrepo release 6 4. EL6. Run yum enablerepoelrepo kernel install kernel lt. You can also Download manually from http elrepo. EL5 or http elrepo. EL6. Or from one of our mirror sites, if one is more conveniently located closer to you. Enjoy Your Bath. There is no need to install the kernel lt firmware package. There are more firmware files contained within the distro package than in the kernel lt firmware package. There is no need to install the kernel lt headers package. It is only necessary if you intend to rebuild glibc and, thus, the entire operating system. If there is a need to have the kernel headers installed, you should use the current distributed kernel headers package as that is related to the current version of glibc. Notes. These packages are provided As Is with no implied warranty or support. Using the kernel lt may expose your system to security, performance andor data corruption issues. Since timely updates may not be available from the ELRepo Project, the end user has the ultimate responsibility for deciding whether to continue using the kernel lt packages in regular service. These packages are not signed for Secure. Boot. If a bug is found when using these kernels, the end user is encouraged to report it upstream to the Linux Kernel Bug Tracker and, for our reference, to the ELRepo bug tracker. By taking such action, the reporter will be assisting the kernel developers, Red Hat and the Open Source Community as a whole. Known Issues. With EL6 there are none currently known. With EL5 there are a number, as shown below. If you have a solution or workaround for one of these issues, please let us know. HAL does not provide battery information affects eg. Gnome. This is a regression in the Linux kernel since 2. Hardware clock devrtc not working. This is a regression in the Linux kernel and is tracked in our bug tracker at http elrepo. Depending upon the hardware being used, the RTC may not be accessible. This can be checked by executing sbinhwclock debug. If the hwclock binary reports that the RTC is not accessible by any means, the patch below fixes the problem after a reboot. A simple temporary work around is to ln sf devrtc. Patch for etcrc.

As a work around to avoid hourly e mail messsages from the cron daemon, you can append 2 1 to the last line of the etccron. See also RHbz 5. Missing dm region hash module. A warning message will be displayed on the system console at boot time about a missing dm region hash module. One workaround to silence the message is to add the nodmraid kernel parameter as part of your kernel options in etcgrub. Another option is to remove the dmraid modules from the initrd if you do not use dmraid, however the mkinitrd options without dmraid and omit raid modules do not work. You will have to comment out three findmodule lines in sbinmkinitrd that reference dm mirror, dm zero and dm snapshot and then recreate your initrd. Search for 1. 32. See also RHbz 1. Some iptables modules fail causing iptables firewall to become effectively disabled. Some iptables modules do not function correctly. This has a knock on effect that iptables restore fails to load any rules if any rule should fail, thus rendering the firewall effectively disabled. Please check your iptables rules carefully to ensure there are no errors and the rules are correctly loaded. See Bug http elrepo.
