I have non-hardened related problems on my laptop since 3.8.4. |
2 |
The integrated e1000e NIC drops carrier unexpectedly. In the logs it seems |
3 |
the NIC gets turned of for a moment, but won't come back despite another |
4 |
message in the log. On that moment the wireless card is enabled |
5 |
temporarily. It seemed to be kinda power-management issue from the |
6 |
beginning. It is very annoying. The NIC cen be brought back by |
7 |
unloading-reloading the driver. Since I'm using a hardened kernel with |
8 |
modules locked, I can't do that. And I also don't want to play that game. |
9 |
It doesn't happen on my server having integrated e1000e NICs on the mobo. |

Recently I had time to dig into that, and have found some relevant links: |

It's a known regression and there's a workaround (sysctl or udev). There |
18 |
is a 5 element patch set also available by Konstantin Khlebnikov. That |
19 |
solves the problem for me. But it's still not committed in the kernel. I |
20 |
don't know if it will be committed or not, or what is the reason it's not |
21 |
already included in the current kernel source. |
22 |
|
23 |
I just wanted to let those know, who may also struggle with such a problem. |
