Perhaps you could repost > around -rc3? Thanks for testing! Nice to see it working on real hw. I'm not sure why you're proposing a 4+ week delay.

JIT is disabled by sysctl by default anyway. -- 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/
