This option cannot be specified with -c option, because the ELF format does not support compressed data." So only elf formatted output from makedumpfile gets processed by crash. @Pratyush, Thanks for testing and verifying the kernel configuration for arm64 makedumpfile. When you say things were working fine for you, what exact makedumpfile command did you use?? Regards, Abhishek
