Subject: Re: [PATCH] soc/tegra: pmc: Fix "scheduling while atomic"

I forgot to mention that this is observed on 3.18 android kernel fork under a 
quite specific condition: EMC scaling enabled and set to the lowest freq, CPU 
max freq reduced. This may cause higher latency on CPU idle enter/exit.

I couldn't reproduce this issue with the upstream kernel, guess some specific 
workload is also required. Any comments? =)
