The patch is totally bogus. irq 0 doesn't say anything about whether the current CPU still works or not. You always need some local interrupt. This basically disables the NMI watchdog for the non boot CPUs. It's even wrong on i386 -- i wonder how that broken patch made it in there. I'll remove it there. -Andi - 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/
