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.
