This has two limitations. One is that for Lustre 2.17 we will be dropping RHEL7 support and second RHEL7 kernels has unique issues that are not present in newer kernels. The reason for the delay to using a newer debug kernel like RHEL8 is that it reports far more problems that needs to be resolved before we move to this target for general testing.</p> Newer distro running a debug kernel.
