We provide these kernels for hardware testing in an effort to identify new/updated drivers which can then be targeted for backporting as kmod packages.
Meanwhile, these kernels may provide interim relief to people with non-functional hardware.
We stress that we consider such kernels as a last resort for those who are unable to get their hardware working using the RHEL-7 kernel with supplementary kmod packages.
These packages are provided "As-Is" with no implied warranty or support.
Using the kernel-ml may expose your system to security, performance and/or 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-ml packages in regular service.
The packages are intentionally named kernel-ml so as not to conflict with the RHEL-7 kernels and, as such, they may be installed and updated alongside the regular kernel. The kernel configuration is based upon a default RHEL-7 configuration with added functionality enabled as appropriate.
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.
The ELRepo Team.
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.
