Question

KDE Neon 16.04 LTS x86_64を実行しています。しばらく作業をすると、ディスプレイはバギーとラグの動作を開始し、サウンドが停止します。Alt+ F1を試行すると、常にnouveauログが出力されます。

ほぼ毎回得た出力と同じように、kern.logからこれをgrepします。

v50cal_spaceエラーは、基本的にGPUがハングしたことを意味し、pushbuf送信のためにIBスペースがなくなったときに発生します。出典： Iliaのコメント。

bugs.freedesktop.org で見つけることができるnv50cal_spaceに関連するバグはほとんどありません。特に：＃93629 、＃999 および＃100567 （CTXSW_TIMEOUTに関連）。
