我在這裡發文是因為我使用的是 Ubuntu，但這可能是一個硬體問題。自從我購買了配備 AMD Athlon(tm) II X4 635 處理器和帶有 ecc 內存的華碩 m4a89td pro/usb3 主機板的新設定以來，我在視頻上出現了卡頓現象。我之前使用的是 ubuntu 11.10，現在使用的是 ubuntu 12.10。查看系統日誌，我發現定期（我只在視頻上註意到，但這種情況總是發生）會發生這種情況：

我有：
- 更新了BIOS；
- 嘗試了所有（真正的）BIOS選項；
- 改變了記憶體；
- 更換了電源供應器和CPU散熱器；
- 嘗試過3.8.1核心。
我現在能做什麼？
請幫我！
謝謝，馬裡奧
