I bet you have CONFIG_CPUMASK_OFFSTACK enabled.
/me is a moron and rumages for a brown paperbag.

Subject: tick: Use zalloc_cpumask_var for allocating offstack cpumasks
From: Thomas Gleixner <tglx@linutronix.de>
Date: Fri, 03 May 2013 20:22:36 +0200
commit b352bc1cbc (tick: Convert broadcast cpu bitmaps to
cpumask_var_t) broke CONFIG_CPUMASK_OFFSTACK in a very subtle way.
Instead of allocating the cpumasks with zalloc_cpumask_var it uses
alloc_cpumask_var, so we can get random data there, which of course
confuses the logic completely and causes random failures.
