I've been seeing this as well, although I'm pretty sure I have profiling disabled. Are you sure it isn't the combination of SMP support and frame pointers that causes this bug to occur? (It looks like profile_pc() takes on a different implementation only if both CONFIG_SMP and CONFIG_FRAME_POINTER is defined.) - 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/
