I tested these two patches and it seemed to get kexec functional: http://lists.infradead.org/pipermail/kexec/2016-February/015440.html http://lists.infradead.org/pipermail/kexec/2016-February/015441.html https://copr.fedorainfracloud.org/coprs/antonym/kexec-tools/build/163086/ Here is a patch posted to kexec-tools upstream: http://lists.infradead.org/pipermail/kexec/2016-February/015445.html I think ubuntu works just because they are using old version of kexec-tools Thanks Dave Antony, can you retest with my patch in comment #2, It seems another problem in the patches in comment #1, but we may have multiple problems in the report though. Patch in comment #2 works for me. But I will appreciate for your further testing because it is the only patch I need to make kexec work. Thanks Dave Antony, sorry, I find my test environment is not correct, I used a latest branch locally. In F23 patch in comment #2 is not necessary. Will see if I can test F23 on a ppc64 machine. I reproduced the problem in F23, patches mentioned in comment #1 works, seems I can not reproduce the problem in my patch (comment #2) with Fedora kernel. But it can be easily reproduced with RHEL kernel in Fedora with latest upstream kexec-tools. Test result like below for me: Fedora kernel load Fedora kernel: need only the ABI v2 patches. Fedora kernel load RHEL kernel: need only ABI v2 patches. Fedora kernel load RHEL kernel with upstream kexec-tools: need both ABI v2 patches and the fs2dt fix in comment #2 So till now for Fedora 23 we should only need the ABI v2 patches, when we rebase kexec-tools in rawhide we may need both. I'm still not sure why the different kernel version matters. Will discuss it in kexec list further. Thanks Dave http://lists.infradead.org/pipermail/kexec/2016-February/015446.html http://lists.infradead.org/pipermail/kexec/2016-February/015447.html http://lists.infradead.org/pipermail/kexec/2016-February/015448.html Above is the upstream patches, but it need review from powerpc people. Any of IBM people in cc list can help review them? Thanks Dave Cool, thanks a lot. Will post patch for Fedora 24 kexec-tools. adi.gangidi, do you need it in Fedora 23? Thanks Dave Yes, if we could please. We're actively working with Fedora 23 and would like do some more testing with it. If it's too much trouble, I can always get a build in copr. Thanks for everyone's help so far! Ok, will fix it in f23 as well. kexec-tools-2.0.10-10.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2016-4e3a1242aa kexec-tools-2.0.10-10.fc23 has been pushed to the Fedora 23 testing repository.
