Could you pull my latest and send me the output with the kexec --debug option added? I guess you are trying to boot the kernel as a UEFI application, which I have not yet done, so not supported. You need to use a UEFI kernel loader. > What's "Modified cmdline" ? That seems to have truncated everything I > passed in. The kexec-tools fs2dt code prints out the Modified cmdline when a node is added to the DT. In this case it is OK, since the arm64 code first adds other nodes. Your new cmdline is added later, but you did not get there do to the failed assertion. -Geoff
