"Total and utter carnage" is a bit of a stretch. Linux hosts that ran applications dependant on nanosleeps needed reboots. Note that this wasn't an issue in 2009, because the poorly tested change in question hadn't yet been made to the Linux kernel.
In 2009, there was a different problem. If the system was under sufficient kernel-related load (such as disk I/O), the kernel's attempt to print an informational message that a leap second had been added caused a kernel deadlock, immediately killing the system. I don't remember any widespread Linux-related leap second issues before that though. -- Chris Adams <cma () cmadams net>
