I'm stuck at the tools side currently. kexec-1.101 just won't load the kernel properly, and kexec-testing from git does not know -j option. I tried hand-patching it, but got lots of scary rejects. Is there chance for a patch against kexec-testing? Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
