The "B" part of the crashkernel boot option is meaningless to sn2 machine and can be very confusing to sn2 users. > > I now have memory reserved, but kernal hanged when executing 'kexec' > command. There must be similar issues in kexec. On further debugging, the kexec dumped core instead at this statement: + elf_rel_set_symbol(&info->rhdr, "__boot_param_base", + &boot_param_base, sizeof(long)); of elf_ia64_load() in kexec/arch/ia64/kexec-elf-ia64.c. Examing the memory i found "__boot_param_base" indeed not present in the symbol table. It seems that purgatory/arch/ia64/entry.S does not have a line +DECLARE_DATAB(____boot_param_base). Is it not needed in other ia64 machines? How does it work in HP machines?
