I could not find any documents on the web. Eric Biederman has been working on 'kexec', which is a fast reboot (Linux boots Linux). See http://www.xmission.com/~ebiederm/files/kexec/ and http://developer.osdl.org/%7Eandyp/kexec/ for some 2.5.[67]x versions. I'm trying to update it to 2.6.0-test3 and make it reboot successfully on my dual P4 machine. Currently it hangs during the reboot. -- ~Randy "Everything is relative." - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
