you could do this and see if this works. stop all apps you care about and then: sync echo o > /proc/sysrq-trigger That will call the kernel directly and immediately power the machine off, if that does not work then the kernel itself does not know how to power it off. And if that does not work, then the fix would be to find a kernel option that changes how the machine gets powered off. There used to be options to do that, I don't know if they are still around.
