I had some oops related to hardened using 4.1.3-hardened-r1, but those are |

I see two similar bug reports, I suppose: |

I've been seeing intel-iommu.c glitches during early boot without any |

| 12 |
it, since it is a really early log message. |
| 13 |
It is possibly related to this bug with the exception that my systems |
| 14 |
works just fine: |
