Hi Dave, My Ubuntu m/c is a 32-bit machine. As seen in uname, it shows "i686". Linux Ubuntu-dev 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 GNU/Linux Ubuntu 10.04.4 LTS In that case, I think the kexec which I built for Ubuntu will work for Android setup too. Regards, Amar I'm presuming that your Ubuntu machine is an x86_64 host, and you're trying to build a 32-bit kexec-tools package that you can install on your Android setup. I am not sure how that is done. But for help on kexec-tools, you should be posting to the kexec-list mailing list: http://lists.infradead.org/mailman/listinfo/kexec This list is specific to the crash utility issues. Dave
