That's a kernel problem, not a busybox one. If you're using APM, the kernel disables it at boot when it's running with more than one processor. You can force it on, only for powering-off, with the option apm=power-off to the kernel. If you're using ACPI, then I don't know why it isn't powering down. It could be because of an older BIOS, blacklisted when in SMP mode. But then you can try activating apm like above. -- lfr 0/0
