5.8 crashkernel=auto setting on UEK R3

If you enable the crashkernel=auto kernel parameter for UEK R3 to simplify Kdump configuration, both dmesg output and /proc/cmdline show crashkernel=NNNM@0M. This behavior is expected for the implementation, where @0M implies the auto setting. The crashkernel=auto parameter is not supported for Xen. (Bug ID 17616874)
