That's clearly a regression. 64-bit CONFIG_NO_HZ is a new feature in v2.6.24. If it happens on 32-bit too and it didnt happen in v2.6.23 32-bit then it's a regression. all this comes from blktrace's original decision of using sched_clock() :-) It's not a global timesource and it's not trivial to turn it into a halfways usable global timesource.
