[plamo:31536] Re: radeonモジュールのロードでハング

[Uetake Sadao]

植竹＠横浜です

ランレベル３で起動しているものとの想定ですが、
radeondrmfbがモニターの適切な解像度を取得できない
ことがあるのかとも考えます。
１．カーネルの起動オプションに
　　video=800x600　等指定してみる。
２．コンソールログインまではradeondrmfbの
　　modesettingをとめてみる
　　１．同様に　nonmodset あるいは radeon.modeset=0を
　　指定してみる。これで従来のVGA16で立ち上がりませんかね。

ランレベル４でしたら、　X のドライバー絡みで追う必要が
でてきます。
