RTL8111 / 8168B Rev 06イーサネットコントローラーがAMD64カーネルで動作しない> 2.6
RTL8111イーサネットコントローラーにも問題があります。 Ubuntu x64ではまったく機能しません。
これは私のカードです：

Subsystem: Gigabyte Technology Co., Ltd Motherboard [1458:e000]
Kernel driver in use: r8168
次のAMD64バージョンでテストしました。
Mint 16 | Kernel 3.11 | r8169 & r8168 not working
Debian 7.2 | Kernel 3.2 | r8169 & r8168 not working
Ubuntu 13.10 | Kernel 3.11 | r8169 & r8168 not working
Ubuntu 12.04.3 | Kernel 3.8 | r8169 & r8168 not working
Ubuntu 12.04.2 | Kernel 3.5 | r8169 & r8168 not working
Ubuntu 12.04.0 | Kernel 3.2 | r8169 & r8168 not working
Ubuntu 11.10 | Kernel 3.0 | r8169 & r8168 not working
Debian 6.0.7 | Kernel 2.6 | r8169 working fine, r8168 working fine
Ubuntu 10.04.4 | Kernel 2.6 | r8169 working with known problems, r8168 working fine
Smos1.2 (Debian) | Kernel 2.6 | r8169 working with known problems, r8168 working fine
結論：RTL8111/8168のrev 06はAMD64カーネル2.6より上では動作しません
- このnicは、すべてのi386カーネルで機能します。
- AMD64のndiswrapperでは動作しませんでした。
回帰：
- ドライバーr8169をブラックリストに載せ、この投稿に基づいて praseodym でdkmに8.036.00をインストールしました。
- launchpad から037.debパッケージも試してみました
- 静的IP/dhcpを試しましたが、接続が機能しません。
私はこの修正されたできるだけ早くを必要とするので、私は0.03 BTCのような小さなBTC寄付を実用的なソリューションに提供したいと思います。
情報とログのリストは次のとおりです。

私は何年も同じ問題を抱えていましたが、カーネルを含むすべてのアップデートで、ネットワークが切断された状態で再起動します。マシンの電源を切り、プラグを引き、電源ボタンを1、2秒間押したままにして、もう一度試してください。それが失敗した場合は、/ etc/udev/rules.d/70-persistent-net.rulesを削除し、通常は再起動してください。
