Hello Guys,

I'm using branch linux-linaro-lsk-android on lsk(https://git.linaro.org/kernel/linux-linaro-stable.git). My arch is armv8.

When I config CONFIG_PREEMPT, The system panic. 

It says "Failed to execute /init". I digged into it and found there was a page fault in atomic path.

And When config CONFIG_PREEMPT_VOLUNTARY or CONFIG_PREEMPT_NONE, it looks well.

Does anyone encounter this situation?
