我有以下提供 USB 3.0 主机控制器的 Express 卡。
05:00.0 USB 控制器：瑞萨科技公司 uPD720202 USB 3.0 主机控制器 (rev 02)
Express 卡在 Win7、Win 10 和 Ubuntu 14.04 下工作正常。在 15.04 下，系统会随机冻结，而
- 取出快速卡。
- 移除连接到它的 USB 设备。
- 使系统从休眠状态恢复。
这尤其令人烦恼，因为这些冻结会导致频繁的 fsck 检查和文件损坏，而这需要强制重启系统。
我的笔记本电脑是 HP DV6T-2000 CT0 型号，配备 Core i7-720QM CPU。有没有什么解决方法或临时解决方案可以尝试？

答案1
我建议你看一下这个Ubuntu 错误报告。在我测试的一台联想 ThinkPad 上，在 BIOS 中禁用 PCIe 电源管理后，uPD720202 不再造成间歇性冻结。该错误报告中建议了其他解决方法，但结果各不相同
