There's only a single bit difference between the expected and actual timer->base value. So either your machine has flakey memory or the percpu data area happened to be separated by 64k.
Is the machine SMP? If so can you please run
nm vmliunx | grep __per_cpu
and send the output? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
