Current kexec-tools has split arch support, and ppc32 is officially broken. I use some old (20070330), patched kexec-tools with ppc32/ and ppc64/ merged into powerpc (alike to Linux). I hope one day I (or somebody else) will find time to cleanup or re-do the patches for the recent kexec-tools, and merge them after all. Though, I didn't look into the patches themselves yet, so I can't tell how much work is pending. -- Anton Vorontsov email: [EMAIL PROTECTED] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
