Yes, thanks for pointing that one out. It looks like the same platform clock
problem is present on that snb platform. I can't verify for sure that that
machine doesn't already have the trace_clock option on the kernel command line
since the boot.txt link over there is broken, but assuming it doesn't we should
also add it to that machine.</pre>
