The following lines in kexec/kernel_version.c cause a crash dump to fail, when the kernel is 4.4.262, or indeed any kernel whose patchlevel is >255. if (major >= 256 || minor >= 256 || patch >= 256) { fprintf(stderr, "Unsupported utsname.release: %s\n", utsname.release); return -1; } return KERNEL_VERSION(major, minor, patch); Regards, Joe _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
