It was the "elfcorehdr" introduced in 2.6.21-rc1. Without specifying it, the elfcorehdr_addr is initialized to ELFCORE_ADDR_MAX. Later, a check in reserve_elfcorehdr will fail: if (elfcorehdr_addr >= ELFCORE_ADDR_MAX) return -EINVAL; Is it supposed to be a physical address to store elf core header? If so, it is not possible for SN to provide a physical address at boot time, just like in the case of crashkernel=X@Y where Y is not used.
