This is made up from: * - bits 0-7 are the preemption count (max preemption depth: 256) * - bits 8-15 are the softirq count (max # of softirqs: 256) * - bits 16-25 are the hardirq count (max # of nested hardirqs: 1024) * - bit 26 is the NMI_MASK * - bit 28 is the PREEMPT_ACTIVE flag That seems to be saying that preemption has been disabled 10 times. The upper 16-bits being all-ones seems to be rather insane - maybe there's an additional __irq_exit() or irq_exit() call somewhere in one of your code paths.
