Probably multiple things. They probably have configurations that are at |
| 10 |
least slightly different. I wouldn't be surprised if there is slightly |
| 11 |
different levels of patching too. |
| 12 |
|
| 13 |
My understanding is that gentoo-kernel differs slightly from a vanilla |
| 14 |
kernel source. |

I'd still be inclined to question hardware. But I agree that difference |
| 19 |
in behavior based on different software is suspicious. I wonder if the |
| 20 |
Gentoo kernel is tickling a bug in the drive's firmware. |

I don't think that older drives would fail in the way that you are |
| 26 |
describing. |

That sounds to me like the drive itself is misbehaving and not |
| 32 |
responding the way the BIOS expects. |

That really sounds like the drive is having a problem. Or that the |
| 37 |
Gentoo kernel is inducing the drive into a state that is a problem. |
| 38 |
|
| 39 |
What happens if you unplug power and data cables from the drive and then |
| 40 |
reconnect them? Does the BIOS then see the drive? |
| 41 |
|
| 42 |
I'm wondering if it's the drive and / or controller that's getting wedged. |

As Mark indicated, you should be able to compare kernel configs. |

I don't remember hearing about such a bug. I wonder if the Gentoo |
| 51 |
kernel is trying to do something slightly different and tickling a |
| 52 |
subtle bug that is causing the drive and / or controller to lock up. |
| 53 |
|
| 54 |
I'd think that it would be easy to remove power and data cables from the |
| 55 |
drive while the computer is powered on to see if that also revives the |
| 56 |
drive. |

Not really. Just threads to chase. |
