 |

I have a machine running hardened sources. Recently, I've discovered that when I put a dvd in the drive, it causes a kernel oops. Below is the output of dmesg.
| Code: |

This doesn't happen with 3.18.9, but it does with 4.0.8.
It also happens with a different external dvd drive with 4.1.4.
I've been using the same config for some time, just doing make oldconfig and accepting the defaults. (I miss pappy's kernel seeds. Is there a replacement?)
How do I start to find out what is wrong with my .config?

| Configuration errors never cause that kind of error. You have encountered a kernel bug. It will need to be fixed by a change to the source. |

| Thanks for the reply. I went to file a bug, someone beat me to it. Next time I'll check bugzilla first. |

If the kernel devs and hardened guys don't have a clue about the culprit, then this does strongly point to "git bisect" IMO  |

I don't see how to use git bisect if the kernels are all patched. Could you explain how to do that? |

Try the same vanilla kernel version and test if the bug exists there too - this case isn't unlikely. |

I already did. gentoo-sources-4.1.4 is fine. |
