ubuntu 11.10 on AO722 が起動時にフリーズする

よくわからないけど症状が以下のサイトに書かれているethenetとwifiの衝突によるものと同じだったので、とりあえずそこに書かれている事を実行してみる。

biosを起動してbootの順位の一位にネットワークブートを持ってくる。そしてネットワークブートがenableになっているのを確認する。これだけ。

症状が再現しないかどうかしばらく様子を見よう。

Ubuntu - Installation of Acer Aspire One 722 (AO722)

Wifi adapter

Under Ubuntu Natty, the Aspire One 722 wifi adapter is fully supported, but presents a very annoying bug, specific to the AO722 hardware.

In fact, every time you try to connect to a wireless network, your netbook may freeze, the only option being a hard reset !

It seems that this bug comes from a conflict between the ethernet and the wireless adapter.

But the good news is that there is a very simple tip to avoid this bug : you need to setup a specific boot order, where the network boot is used first. With this setup, the ethernet adapter will be configured in a way that there won't be any conflict with the wifi adpater at the time of wireless network connexion.

To do so, reboot your netbook and enter the BIOS by typing F2 at boot time.

First, set the Network Boot as the first one in the boot priority order :

Next, be sure that Network Boot is enabled :
