Kernel 2.6.32-573.22.1.el6.x86_64 and load averages

Anyone else running into any issues with kernel 2.6.32-573.22.1.el6.x86_64?
We recently upgraded a portion of our lab environment to kernel-2.6.32-573.22.1.el6.x86_64 during our routine patching cycle and after reboot we are noticing a subset of systems reporting high Load Averages .

Upon closer inspection, reverting the a previous kernel, we observe more historical load averages. I am aware there was a change to the calc method for load averages in 2.6.32-573.20.1.el6 but this seems like it should have resolved an issue rather than create a new one.

• [sched] kernel: sched: Fix nohz load accounting -- again (Rafael Aquini) [1300349 1167755]

This system has no running user processes and yet reports a higher load average on kernel 2.6.32-573.22.1.el6.x86_64

with kernel 2.6.32-573.18.1.el6.x86_64
#> uptime

About to pull the trigger on rolling our lower environment back to 2.6.32-573.18. Have a support case open already too, but waiting in queue.

TIA for any input
