For stability, performance, etc ... we try our best to avoid the distro kernels. Its fairly easy to crash a number of them under even moderate file/block serving loads. Couple this with a number of the ancient drivers they use for RAID and network systems, it takes years before you can take advantage of functionality (PCIe error reporting, bug fixes, performance tweaks, etc.) in the latest drivers as compared with what the distro kernels ship. Do remember that the distro kernels are tweaked for their most common workloads.
