I had some issues with 3.2.0-rc2 when used as linux-kexecboot, that's why I've added this, but later found out that it's really a bit incomplete, that's why I have followup patch for this: https://gitorious.org/shr/meta-handheld/commit/6bc710615b587fc0bfd8fc4372cad0de5599dd82?format=patch But with latest SRCREV it works again, so in theory I don't need it, but still it would be usefull to have easy way to debug even this stage (maybe you still remember older kernel version where it worked fine as 3rd stage and failed to boot as 2nd stage..). BTW: here is upgrade to 3.2.0-rc2 with those changes to linux-kexecboot.inc applied https://gitorious.org/shr/meta-handheld/commit/27ca3d24353a5473f4f1aade00ba7a52b667e28c?format=patch (be aware that I do rebase that branch sometimes so if those commits are not valid anymore just look at last few commits in that branch).
