![Ubuntu 14.04 Atheros AR922X [168c:0029] Wifi PCI 内存区域保留错误](https://linux22.com/image/879801/Ubuntu%2014.04%20Atheros%20AR922X%20%5B168c%3A0029%5D%20Wifi%20PCI%20%E5%86%85%E5%AD%98%E5%8C%BA%E5%9F%9F%E4%BF%9D%E7%95%99%E9%94%99%E8%AF%AF.png)
我已经为此苦苦挣扎了一段时间。无法让我的 PCI Wifi 卡在装有 Ubuntu 14.04 的台式机上运行。我通过“wireless-info”脚本附加了 wireless-info.txt。请注意 dmesg 部分的第一行“ath9k 0000:05:00.0: PCI 内存区域保留错误”。似乎是驱动程序的问题？疯狂地在 Google 上搜索，但无济于事。有人知道如何修复这个问题吗？我需要继续使用 14.04，因为我正在运行依赖于此版本的软件。
