我已经在这台机器上安装了 Ubuntu 13.04（最新更新，内核 3.8.0-25-generic）并遇到了几个问题：
当我重新启动笔记本电脑时，显示器显示：
[ 9.171781] INFO @wl_cfg80211_attach : Registered CFG80211 phy
我不知道这是否是此组合中已知的错误。此问题在其他硬件配置中很常见。

我收到消息了。
我希望有人能帮助我识别这是否是一个错误。
答案1
根据此评论：
我在启动时收到了同样的消息，但我不认为这是一个错误。只是启动时的消息很烦人
下一个：
对我来说是相同的 INFO 消息：每次启动时，就在 Ubuntu 启动画面之前，我都会收到该消息。
只是一条消息，没什么可害怕的。
